Question

The radius of a cylindrical water tank is 5.5ft, and its height is 13ft. What is the volume of the tank?

Use the value 3.14 for pie , and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.

Answer 1

The volume of the tank is 1235ft³

Explanation:

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 13ft

π = 3.14

r = radius = 5.5ft

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (5.5ft)²) * 13ft

v = (3.14 * 30.25ft²) * 13ft

v = 94.985ft² * 13ft

v = 1234.805ft³

Round to the nearest whole number

v = 1234.805ft³ = v = 1235ft³
