The total surface area of a right circular cylinder with radius of the base 7 cm and height 20 cm, is :

Answer: Option D

Radius and height of a right circular cylinder is 7 cm and 20 cm respectively
Total surface area of right circular cylinder :
$$\begin{array}{rl}& =2\pi rh+2\pi r^2\\ & =2\pi r\left(h+r\right)\\ & =2\times \frac{22}{7}\times 7\left(20+7\right)\\ & =2\times 22\times 27\\ & =1188sq.cm\end{array}$$
