Question

An oil storage tank is a cylinder with a height of 50 feet and a diameter of 20 feet. What is the volume of the tank? Use 3.14 for Pi. A cylinder has a height of 50 feet and diameter of 20 feet. 15,700 cubic feet 39,250 cubic feet 62,800 cubic feet 78,500 cubic feet

Answer 1

15,700 cubic feet

Explanation:

Answer 2

15,700 cubic feet

Explanation:

The formula for the volume of a cylinder is ...

V = πr²h

where r is the radius (half the diameter), and h is the height.

Put the given numbers into the formula and do the arithmetic.

V = (3.14)(10 ft)²(50 ft) = 15,700 ft³

__

An estimate of the arithmetic will get you to the right answer choice:

πr²h = π(100)(50) = 5000π ≈ 3×5000 = 15,000 . . . . close to 15,700
