Question

A cylinder tank has a radius of 15 ft and a height of 45 ft. How many cubic ft of water can the tank hold? A) 127,170 cu ft. B) 15,896.25 cu ft. C) 31,792.5 cu ft. D) 675 cu ft

Answer 1

volume=height times pi times radius^2
aprox pi=3.14 for this problem
height=45
radius=15

so
volume=45 times 3.14 times 15^2
volume=141.3 times 225
volume=31,792.5 cu ft

answer is C
