Question

richgall____ · Answer

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 5 inches. The height of the cone is 15 inches.

Use pi = 3.14.

What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.

1st of all diameter=8
so radius=4  cuz radius is half of diameter
$$volume_{cylinder}=pi \times r^2 \times h$$$$volume_{cylinder}=3.14\times 4^2 \times 5$$

$$volume_{cone}=\frac{ \pi \times r^2 \times h }{ 3 }$$$$volume_{cone}=\frac{ 3.14 \times 4^2 \times 15 }{ 3 }$$$$volume_{cone}=3.14 \times 4^2 \times 5$$

clearly volume of cylinder=volume of cone
