Question

find the total surface area of the cylinder having the following dimensions. radius of base = 35 cm and height = 2.5m

Answer 1

$2 \times pi \times {r}^{2} + 2\pi \times r \times h$
84665.92 square centimetre

Answer 2

$\huge\bold\green{Solution :\longrightarrow}$

Given,

Radius (r) = 35 cm

Height (h) = 2.5 cm

Now,

TSA of the cylinder

$\mathsf{= 2\pi \: r \: (h + r) }\\ \\ \mathsf{= 2 \times \frac{22}{7} \times 35 \: \: (2.5 + 35) \: {cm}^{2}}$

$\mathsf{= 220 \times 37.5 \: {cm}^{2} }\\ \\ \mathsf{= 8250 \: {cm}^{2} }$
