Question

A cylindrical cardboard tube with a diameter of 8 centimeters and a height of 20 centimeters is used to package a gift. A cylinder has a height of 20 centimeters and a diameter of 8 centimeters. What is the approximate volume of the tube? Round to the nearest whole cubic centimeter.

Answer 1

Answer: 1005 cm^3

Step-by-step explanation: Got it correct on test!

Answer 2

1005.3 cm³

Explanation:

Let's begin by listing out the given variables:

diameter (d) = 8 cm ⇒ r = 4 cm, height (h) = 20 cm

Formula for volume of cylinder is, πr²h

V = πr²h = π * 4² * 20 = 1,005.31 cm³

V ≈ 1005.3 cm³
