Question

The volume of a cylindrical tank of radius r and height h is given by  Find the volume of a cylindrical tank of radius 2 ft and height 8 ft.

Quizplus · Accepted Answer

To find the volume of a cylindrical tank with radius 2 ft and height 8 ft, we substitute r = 2 and h = 8 into the formula:

V = πr^2h = π(2^2)(8) = 32π

Using the decimal approximation of π = 3.14, we have:

V ≈ 32(3.14) ≈ 100.48

Rounding to two decimal places gives:

V ≈ 100.48
