Question

Find the area of curved surface and total surface area of the cylinder whose heights and radii are given below:
$h=10cm,r=7cm$

Answer 1

$CSA=2\pi \times 10\times 7=2\times 22\times 10=440{cm}^2$

$TSA=2\pi rh\times {2\pi r}^2=440+2\times \pi \times 7\times 7=440+308=748{cm}^2$

Hence, this is the answer.
