Question

A water tank is cylindrical whose inside radius is 3.5 m and depth is 21m .how many kilo litres of water can it hold.

Answer 1

Example 1: A cylindrical water storage tank has an inside base radius of 7m and depth of 11 m. Find the capacity of the tank in kiloliters (1kl = 1m3). Solution: Base radius: r = 7 m

Answer 2

volume of cylindrical tank =22/7×3.5×3.5×21=1617/2mcube
1m3=1000li
so, 1617/2m3=1000×1617/2=808500kilo l
