A cylinder has a volume of 320 cubic inches and a height of 5 inches. What is the radius of the cylinder?
O A. 4 inches
B. 8 inches
C. 16 inches
D. 32 inches

The radius is 8 inches

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

Assuming you mean 320 pi for the volume

320  pi = pi r^2 ( 5)

320 =5pi r^2

Divide each side by 5pi

320 pi / 5pi = 5 pi r^2 / 5pi

64 = r^2

Take the square root of each side

sqrt(64) = sqrt(r^2)

8 = r

The radius is 8 inches

Step-by-step explanation:

The volume is 320 in³.

The height is 5 in.

Solving for .

Dividing both sides by 5.

Dividing both sides by .

Taking the square root of both sides.

The radius is 4.51 inches.
