Question

A cylinder has a base diameter of 4 centimeters and a height of 4 centimeters. What is its volume in cubic centimeters, to the nearest tenths place

Answer 1

50.3 cm³

Explanation:

Use the cylinder volume formula:

V = r²h, where r is the radius and h is the height.

Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.

Plug in the radius and height into the equation:

V = r²h

V = (2²)(4)

V = 16

V = 50.3 cm³

Answer 2

50.3 cm³

Explanation:

Use the cylinder volume formula:

V =
`\pi`r²h, where r is the radius and h is the height.

Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.

Plug in the radius and height into the equation:

V =
`\pi`r²h

V =
`\pi`(2²)(4)

V = 16
`\pi`

V = 50.3 cm³
