Question

A test tube is cylindrical in shape with a length of 152 mm and a radius of 6.5 mm. What is the volume of the test tube? Report your answer in mm3 but do not include the unit mm3 in your answer box. Round your answer to the nearest whole number and do not include commas in your answer. The formula for volume of a cylinder is V=πr2h.

Answer 1

Based on the given information, the volume of the test tube is approximately 20175
`mm^3`

How to calculate the volume of the test tube

To calculate the volume of the test tube, use the formula for the volume of a cylinder:

`V = \pi r^2h`

Given:

Length (h) = 152 mm

Radius (r) = 6.5 mm

Substituting the values into the formula:

`V = \pi (6.5^2)(152)\\V ≈ 3.14159 * (6.5^2) * 152`

V ≈ 3.14159 * 42.25 * 152

V ≈ 20175.2910
`mm^3`

Rounded to the nearest whole number, the volume of the test tube is approximately 20175
`mm^3` (without including the unit in the answer box).

Answer 2

20165

Explanation:

Given:

Length/height (h) of cylindrical test tube = 152 mm

Radius of cylindrical test tube = 6.5 mm

Volume =
`\pi r^2h`

Required:

Volume of cylinder to nearest whole number

Solution:

The volume is given as
`V = \pi r^2h`

Take π as 3.14 and plug the values of r and h into the volume formula.

`V = 3.14*6.5^2*152`

`V = 3.14*6.5*152 = 20165.08`

Volume of the test tube = 20165 mm³ (nearest whole number)
