Question

The diameter of a cylindrical construction pipe is 3 ft. If the pipe is 14 ft long, what is its volume?Use the value 3.14 for n, and round your answer to the nearest whole number.Be sure to include the correct unit in your answer.3 ftO14 ft

Answer 1

The formula for calculating the volume of a cylinder is expressed as

Volume = pi x radius^2 x height

From the information given,

diameter = 3

radius = diameter/2 = 3/2 = 1.5

height = 14

pi = 3.14

By substituting these values into the formula, we have

Volume = 3.14 x 1.5^2 x 14 = 98.91

Rounding to the nearest whole number,

Volume = 99 ft^3
