Answer:
[tex]A=522.97\ \text{cm}^2[/tex]
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 :
[tex]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[/tex]
So, the surface area of the cylinder is [tex]522.97\ \text{cm}^2[/tex]
