Question

Work our the surface area of this cylinder?

Answer 1

`A=522.97\ \text{cm}^2`

Explanation:

Given that,

The diameter of the cylinder, d = 8 cm

Radius, r = 4 cm

Height of the cylinder, h = 16.8 cm

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

`A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2* (22)/(7)* 4* (4+16.8)\\\\=522.97\ \text{cm}^2`

So, the surface area of the cylinder is
`522.97\ \text{cm}^2`
