D. 537.21 units 3
Answer:
C
Step-by-step explanation:
V=1/3(3.14)(r)^2(h)V=1/3(3.14)(3)^2(19)V=57×3.14v=179.07unit 3The volume of a cone with a radius of 3 and a height of 19 is 179.07 cubic units.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
We have to find the volume of a cone with a radius of 3 and a height of 19.
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
r=3 and h=19
We have to find the space in the cone with radius 3 and height 19.
The formula for volume of the cone is V=1/3πr²h
We have to plug in the r and h values in formula.
V=1/3×3.14×(3)²×19
=1/3×3.14×9×19
=536.94/3
=179.07 cubic units
Hence, the volume of a cone with a radius of 3 and a height of 19 is 179.07 cubic units.

Determine the amount of stone needed to build one of the pyramids with a height of 145 m and a square base with a side length of 230m? Find the volume.
Answer:
Step-by-step explanation:
We would apply the formula for determining the volume of a square based pyramid which is expressed as
Volume = 1/3 × base area × height
From the information given,
Side length = 230m
Height = 145m
Since the base is a square,
Base area = 230² = 52900
Therefore,
Volume = 1/3 × 52900 × 145
Volume = 2556833.3 cubic meters
The amount of stone needed is expressed in volume.

The rectangle below has an area of x^2-7x+10x square meters and a width of x-5x meters. What expression represents the length of the rectangle?
Answer:
The area of a rectangle is:
\sf A=lw
Plug in what we know:
\sf x^2-7x+10=l(x-5)
Factor the left side:
\sf (x-2)(x-5)=l(x-5)
Divide (x - 5) to both sides:
\sf l=\boxed{\sf x-2}
So the length is x - 2 meters.

x = 11.6

y= 23.2
x = 18.3
y = 36.6
Answer:
(C)x=11.6, y=23.2
Step-by-step explanation:
Using Theorem of Intersecting Secant and Tangent
Applying this theorem in the diagram, we have:
[tex]TQ$ X TP=TR^2[/tex]
[tex]10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6[/tex]
Next, we apply Theorem of Intersecting Chords
PV X VQ=SV X VR
4 X x= 2 X y
Recall earlier we got: x=11.6
2y=4 X 11.6
2y=46.4
Divide both sides by 2
y=46.4/2=23.2
Therefore: x=11.6, y=23.2

This net consists of a square and 4 identical triangles. What is the surface area of the solid this net can form?
144 square inches
184 square inches
224 square inches
264 square inches
Answer: C, 224 inches squared
Step-by-step explanation:
When formed into a solid, the triangles are folded upwards to make a pyramid. You can find the surface area by finding the areas of the individual shapes.
There are four triangles with a height of 10 inches and a base of 8 inches.
There is one square with a side length of 8 inches.
Triangle area formula : A = (b * h) / 2
Square area formula: A = s^2
(10 * 8) / 2 = 40
8 ^ 2 = 64
There are four triangles with area of 40 and one square with area of 64.
40 + 40 + 40 + 40 + 64 = 224 inches squared. The correct answer choice is C.
The surface area of the pyramid is 224 in².
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given net will form a square pyramid, so we will find the surface area of the square pyramid.
Therefore,
The area of the pyramid = side² + 2 × side × height
= 8² + 2 × 8 × 10
= 64 + 160
= 224
Hence the surface area of the pyramid is 224 in².
