The perimeter of figure is,
P = 24.50 feet
And, the area of the figure is,
A = 45.68 feet²
Since, we know that;
The perimeter of a circle is equal to the circumference
C = 2πr
where,
C is the circumference of the circle
r is the radius of the circle
we have, r = 4 feet
substitute in above equation,
C = 2 × 3.14 × 4
C = 25.12 feet
In the figure
the triangle ABC is a right triangle,
Applying the Pythagoras Theorem find the length side CB
CB² = AB² + AC²
we have, AB = AC = 4 feet
CB² = 4² + 4²
CB² = √32
CB = 5.67 feet
The perimeter of the figure is equal to 3/4 of the circumference plus the length side CB
so we get;
P = 3/4 (25.12) + 5.66
P = 24.50 feet
Now, we know that,
the area of a circle is equal to
A = πr²
where, r is the radius of the circle
we have, r = 4 feet
substitute
A= 3.14 × 4²
A = 50.24 feet²
the area of the triangle ABC is equal to,
A = 1/2 bh
Here, b = √32 ft
h = √32/2 ft
Hence, WE get;
A = 1/2 x √32 x √32/2
A = 8 feet²
Since, the area of the figure is equal to 3/4 of the area of the circle plus the area of the triangle ABC,
A = 3/4 (50.24) + 8
A = 45.68 feet²

What is the surface area of the triangular prism 4 ft 5 ft 2 ft 3 ft
Answers
The surface area of the triangular prism is 137ft².
What is the surface area of the triangular prism?To get the surface area of a triangular prism, we will calculate the area of each face and then sum them up.
Base area = (4 ft * 5 ft) / 2
Base area = 20ft/2
Base area = 10 ft²
Since triangular prism has two triangular bases, the total area of the triangular bases is:
= 2 * Base area
= 2 * 10 ft²
= 20 ft².
Perimeter of the triangular base:
= 4 ft + 5 ft + 4 ft
= 13 ft
Face area = Perimeter * Height
Face area = 13 ft * 3 ft
Face area = 39 ft²
The total area of the rectangular faces is:
= 3 * Face area
= 3 * 39 ft²
= 117 ft².
The Surface area of the triangular prism will be:
= Total area of triangular bases + Total area of rectangular faces
= 20 ft² + 117 ft²
= 137 ft².

The measure of central angle DBC is 68 degree.
Hence, option C is correct.
In the given figure,
Measure of intercepted arc = 68 degree,
We have to find the measure of central angle DBC
We know that,
When two circle radii intersect in the center of a circle, they produce a vertex. These circle arms may begin at two distinct positions along the arc of such a circle. The two radii cross to produce a central angle, which serves to divide a circle into separate sectors.
A central angle is generated in the center of a circle when two radii within the circle overlap. As previously stated, a central angle in geometry is one whose vertex forms at the canter of the circle and whose arms cross the circle at two separate positions.
By connecting these two locations, an arc on the circle is formed. As a result, a central angle is the angle formed by an arc in the center of a circle.
Thus by property of central angles,
central angle = measure of intercepted arc
Hence,

A publishing company conducted a survey asking readers whether they use e readers. Of the 3000 readers surveyed, 1954 said they read books on e reader. The approximate sample proportion is? Which means that? %of the readers surveyed don’t use e readers
Answers
Approximately 34.87% of the readers surveyed don't use e-readers.
To find the approximate sample proportion of readers who use e-readers, we divide the number of readers who said they read books on e-readers (1954) by the total number of readers surveyed (3000):
Approximate sample proportion = Number of readers who use e-readers / Total number of readers surveyed
Approximate sample proportion = 1954 / 3000 ≈ 0.6513
To express this as a percentage, we multiply the sample proportion by 100:
Approximate sample proportion as a percentage = 0.6513 × 100
= 65.13%
Therefore, the approximate sample proportion of readers who use e-readers is approximately 65.13%.
This means that approximately 65.13% of the readers surveyed use e-readers.
To determine the percentage of readers who don't use e-readers, we subtract the sample proportion from 100%:
Percentage of readers who don't use e-readers = 100% - 65.13%
= 34.87%

An empty rectangular tank measures 55 cm by 35 cm by 30 cm. Mr Tay emptied 62 l of water from another container into the rectangular tank. How much water overflows from the rectangular tank? Give your answer in litres and millilitres
Answers
Answer: The water that overflows from the rectangular tank is 4.25 liters or 4250 milliliters.
Step-by-step explanation: To calculate the volume of the rectangular tank, we need to multiply its length, width, and height. The measurements are given in centimeters, so we need to convert the result to liters.
Volume of the rectangular tank = length × width × height
= 55 cm × 35 cm × 30 cm
Converting the volume to liters:
1 liter = 1000 cubic centimeters (cm³)
Volume of the rectangular tank = (55 cm × 35 cm × 30 cm) / 1000
= 57750 cm³ / 1000
= 57.75 liters
Mr. Tay emptied 62 liters of water into the rectangular tank. Since the tank's volume is only 57.75 liters, the excess water will overflow.
Overflow = Volume of water emptied - Volume of the rectangular tank
= 62 liters - 57.75 liters
= 4.25 liters
To convert the overflow from liters to milliliters:
1 liter = 1000 milliliters (ml)
Overflow in milliliters = 4.25 liters × 1000
= 4250 milliliters

Find m/JKL in OE.
A. 53°
B. 37°
C. 106°
D. 43°
L
E
74°
K
Answers
Answer:
A
Step-by-step explanation:
the inscribed angle JKL is half the measure of its intercepted arc
the sum of the arcs in a circle in a circle = 360°
since LK is a diameter the arc KL is equal to the measure of its central angle , that is
arc LK = 180° , then
LJ + JK + KL = 360°
LJ + 74° + 180° = 360°
LJ + 254° = 360° ( subtract 254° from both sides )
LJ = 106°
Then
∠ JKL = [tex]\frac{1}{2}[/tex] × 106° = 53°
ABC is equal to DEF and AB is equal to EF what type of triangle is ABC
Answers
Based on the information provided, the triangle ABC is an Isosceles triangle.
Understanding Isosceles TriangleIf triangle ABC is equal to triangle DEF and AB is equal to EF, it means that the corresponding sides and angles of the two triangles are congruent.
Based on the information given, we can conclude that triangle ABC is an isosceles triangle. An isosceles triangle is a triangle that has two sides of equal length. In this case, sides AB and EF are equal in length, making triangle ABC isosceles.
