Question

Find Tsa of a cylunder radius 35cm and height is 2.5cm

Answer 1

Given Radius of the cylinder = 35cm

Given height of the cylinder = 2.5cm

To find - Total Surface area (T.S.A) of the cylinder.

Total Surface area of the cylinder = 2πr(r + h)

Where, The value of π is constant, It can either be 3.14 or 22/7, r stands for radius of the cylinder and h stands for the height of the cylinder.

$so \: tsa = 2 \times \frac{22}{7} \times 35(35 + 2.5) \\ \\ 2 \times \frac{22}{7} \times 35 \times 37.5 \\ \\ 2 \times 22 \times 5 \times 37.5 \\ \\ convert \: decimal \: into \: fraction \\ \\ 2 \times 22 \times 5 \times \frac{75}{2} \\ \\ 22 \times 5 \times 75 \\ \\ 8250 \: {cm}^{2}$
