A cylinder has a base radius of 4m and a height of 6m. What is its volume in cubic m,
to the nearest tenths place?
Answer:
301.4
Step-by-step explanation:
Volume of a cylinder=pi*[tex]r^{2}[/tex]*h. Assuming you want 3.14 for pi, we can substitue the 4m for r, 6 for h and 3.14 for pi.
V=3.14*[tex]4^{2}[/tex]*6
V=301.44
Since you want to round to nearest tenths, the answer is 301.4
The volume of the cylinder with the given value of radius and height to the nearest tenth place is 301.4 cubic meters.
What is a cylinder?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )
Given the data in the question;
Radius r = 4mHeight h = 6mVolume of the cylinder V = ?We substitute our values into the expression above.
V = π × r² × h
V = 3.14 × (4m)² × 6m
V = 3.14 × 16m² × 6m
V = 301.4m³
The volume of the cylinder with the given value of radius and height to the nearest tenth place is 301.4 cubic meters.

A fountain is made up of two semicircles and a quarter circle. Find the perimeter of the fountain. Round answers to nearest tenth. The diameter for the semicircles is 10
Answer:
39.275
Step-by-step explanation:
the diameter of the semicircle is 10
A semicircle is half a circle, and a quarter circle is 1/4 of a circle.
Perimeter of a semicircle is ¶d/2
= 3.142 x 10/2 = 3.142 x 5 = 15.71
For 2 semicircles that will be 15.71 x 2 = 31.42
For the quarter circle, perimeter is ¶d/4 = 3.142 x 10/4 = 3.142 x 2.5 = 7.855
Total perimeter = 31.42 + 7.855 = 39.275

Answer:
16 units
Step-by-step explanation:
The y intercept is when the x value is 0
f(0) = 2(0)+8 = 8
The y intercept of f(x) is 8
g(0) = -8
The y intercept of g(x) is -8
The distance between f(0) and g(0)
8 - -8 = 8+8 = 16

Answer:
A) 25
Step-by-step explanation:
Set the ratios. Place the similar sides equal to each other.
Sides:
AB/CB = XY/ZY
Plug in corresponding numbers to the corresponding sides:
50/40 = x/20
Simplify. Divide 2 from both the numerator and denominator of the first fraction to get common denominators:
(50/40)/(2/2) = 25/20
25/20 = x/20
x = 25
A) 25 is your answer.

Step-by-step explanation:
the length of the side of a square is equal to the perimeter of the square divided by four.
which shows the correct graph relating the perimeter of a square on the x-axis to the side of a square on the y axis
Answer:
The last image (The one going through points (4,1) and (8,2))
Step-by-step explanation:
If the side length is y, and the perimeter is x, x is equal to that value times 4. This means the table of points would look like this:
x y
4 1
8 2
12 3
And so on. The only graph that is going through these points is the last one. The third graph is wrong because it's the opposite, (1,4) instead of (4,1), and the perimeter will be greater than the side length.

Answer:
On the circle
Step-by-step explanation:
Because all of the points on a circle are equidistant from the center, if a circle has a radius of 10 then all of the points are 10 units from the center. Using the Pythagorean Theorem, you know that the distance from (4,0) to (-2,8) is:
[tex]\sqrt{(4-(-2))^2+(8-0)^2}=\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10[/tex], meaning that it is on the circle. Hope this helps!

Step-by-step explanation:
The area of a rectangle is given by
lw = A
11.8x = 47.6
Divide each side by 11.8
11.8x/11.8 = 47.6/11.8
x =4.033898305
To the nearest tenth
x = 4.0
Answer:
algebraic equation; 11.8x = 47.6
width = 4.0
Step-by-step explanation:
solve the algebraic equation to get x, the width.
11.8x = 47.6
divide both sides by 11.8 and you will get 4.0338.....
round off to nearest tenths to remain with 4.0
How do I find the area ?
Answer:
7.74 cm^2
Step-by-step explanation:
The length of the side of the square is 3+3 = 6
The area of the square is
A =s^2 = 6^2 = 36
The area of the circle is
A = pi r^2 where the radius is 3
(3.14) 3^2 =28.26
Subtract the area of the circle from the area of the square to get the shaded area
36-28.26 = 7.74 cm^2

The scale drawing of a rectangular room measures 10cm long by 6cm wide. The actual width of the room is 9 metres. What is the actual perimeter of the room, in metres?
Answer:
48 meters
Step-by-step explanation:
The first thing is to calculate the scale, since we know both widths it is possible:
we pass the 9 meters to centimeters = 900 cm
900/6 = 150
So the scale would be 1: 150
Which means that the length is 150 times bigger.
10 * 150 = 1500cm or what equals 15m
the perimeter is the sum of all the sides, therefore:
P = 15 + 15 + 9 + 9
P = 48
Which means that the perimeter of the room is 48 meters
Ernesto wants to buy a snack from the vending machine. The vending machine has 5 different kinds of chips, 8 different candy bars, and 2 different kinds of cookies. If he chooses one at random, what is the probability that it is a cookie?
Answer:
The probability that it is a cookie is [tex]\frac{2}{15}[/tex]
Step-by-step explanation:
To find the probability that it is a cookie if he chooses one at random;
probability = required outcome / all possible outcome
The all possible outcome will be gotten by adding up all the snacks. that is;
required outcome = 5 + 8 + 2 = 15
The required outcome is the snack he chooses, that is; required outcome = 2
Probability (of choosing a cookie) =required outcome / all possible outcome
=[tex]\frac{2}{15}[/tex]
Therefore, the probability that it is a cookie is [tex]\frac{2}{15}[/tex]
