Question

the base radius and height of a right circular cylinder are 5cm and 10cm it's total surface area is?​

Answer 1

Answer:-

To find T.S.A. of a right circular cylinder:-

2πr(r+h)

$= \sf2 \times \frac{22}{7} \times 5 \times (5 + 10)$

$= \sf2 \times \frac{22}{7} \times 5 \times 15 = 471.42$

So T.S.A. of give cylinder is 471.42
