Question

A cylinder has a volume 45pi and radius 3. What is it’s height?

Answer 1

The height is 5

Explanation:

Given data:

Volume V = 45 π and radius r = 3 units

The formula for the volume of the cylinder is V = B · H

Base of the cylinder is:

B = r² π = 3² π = 9 π

From the formula V = B · H we get H:

H = V / B = 45 π / 9 π = 5 units

H = 5 units

Answer 2

the answer is 15

Explanation:

Given data:

Volume V = 45 π and radius

r = 3 units The formula for the volume of the cylinder is V = B · H

Base of the cylinder is:

B = r² π = 3² π = 9 πFrom the formula V = B · H we get H:H = V / B = 45 π / 9 π = 5 units

H = 5 units
