Question

A cylindrical water tank has a radius of 14.5 feet and a height of 7.5 feet. Which value is the best estimate of the volume of the water tank? Round your answer to the nearest tenth of a foot.

Answer 1

C= 2π14.5

C= 91.1061869

91.1061869 X 7.5 = 683.296402

A of a circle = πr squared

as the are two circles to a cylinder 2πr squared

2 X π X 14.5 = 1321.03971

add together

1321.03971 + 683.296402 = 2004.33611 ft squared
