Question

Find total surface area of cylinder is R = 7 cm and H = 10 cm​

Answer 1

Explanation:

Given radius , r = 7cm

and height , h = 10cm

Surface Area of Cylinder

`= 2\pi {r}^(2) + 2\pi \: rh \\ = 2\pi( {7}^(2) ) + 2\pi(7)(10) \\ = 2\pi(49) + 2\pi(70) \\ = 98\pi + 140\pi \\ = 238\pi {cm}^(2)`

I will leave it in terms of pi as i am not sure how you want to leave your answer as.
