The volume of a cylinder is 5500 m$$^3$$​. Find its diameter if the cylinder is 70 m high.

Correct option is A

Given:

The volume of a cylinder is 5500 m$$^3$$​​. 

Height of the cylinder = 70 m 

Formula Used:

Volume of the cylinder = $$\pi r^2 h$$ 

Solution:

​$$\pi r^2 h$$  = 5500 

​$$\frac{22}{7} r^2 \times 70 = 5500 \\\ \\220 r^2 = 5500 \\\ \\r^2 = 25 \\r = 5$$

Diameter of cylinder = 2r = 10m
