Question

A cylinder has a diameter of 10 inches and a height four times its radius. What is its volume?

Answer 1

Answer:

500π ≈ 1570.796

Step-by-step explanation:

diameter = 10

radius = diameter / 2 = 10 / 2 = 5

height = 4 * radius = 4 * 5 = 20

volume = π * height * (radius)² = π * 20 * (5)² = 500π ≈ 1570.796

Answer 2

Answer:

1570.8 in ^3

Step-by-step explanation:

The radius of a circle is simply half the diameter so the radius is 5.

10/2=5

Therefore, the height is 20

4x5=20

The formula for the volume of a cylinder is πr^2h

π = π

r= radius

h=height

so π(5)^2(20) = 1570.796327 in ^3

for sig figs, 1570.8 in ^3

hope this helps :)
