Question

The volume of a cylindrical water tank is 26,374.14 cm3 . The area of the base of the cylinder is 720.63 cm2. What is the length of the water tank? (Use 3.14 for π .)

Answer 1

If cylinder base = 720.63 (PI * r^2)
PI* r^2 = 720.63
r^2 = 720.63 / PI
r^2 = 229.38
radius =  15.145

Cylinder Volume   =   π • r² • height
Height = Volume / (PI * r^2)
Height = 26,374.14 / 720.63
Height = 36.5987261146
radius =  15.145
