Question

Find the Volume of the Cylinder having a radius of 4 inches and whose height is 10 inches.

Question 7 options:

160π in.3


40π in.3


16π in.3


160π in.2

Answer 1

`160\pi`
`in^3`

Explanation:

Use the formula for the volume of a cylinder with circular base of radius R:

`Vol= \pi R^2 H`

Where R is the radius of the circular base (in our case 4 inches)

and H is the cylinder's height (in our case 10 inches)

Therefore:
`Vol= \pi (4in)^2 (10in)=\pi (16)(10) in^3= 160 \pi`
`in^3`
