Question

Work our the surface area of this cylinder?

Answer 1

Answer:

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

Step-by-step 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 :

$A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2\times \dfrac{22}{7}\times 4\times (4+16.8)\\\\=522.97\ \text{cm}^2$

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