Question

Find the surface area of the cylinder.

Answer 1

`A=227.84\ inch^2`

Explanation:

Given that,

The diameter of the cylinder, d = 5 inch

Hight, h = 12 m

Radius, r = d/2 = 2.5 m

We need to find the surface area of the cylinder. The formula for the surface area of the cylinder is given by :

`A=2\pi rh+2\pi r^2\\\\A=2* (22)/(7) * 2.5* 12+2\pi * 2.5^2\\\\A=227.84\ inch^2`

So, the lateral surface area of the cylinder is equal to
`227.84\ inch^2`.
