Answer 1

$\huge \underline \mathsf \red {Solution:-}$

Let the height and radius of the cylinder be h and r cm respectively.

Given:

• Height is 2m = 200cm

As, circumference of base = 220

2πr = 220

➠ $\mathsf {2 \times\frac{22}{7} \times r = 220}$

r = 35 cm

➠ $\mathsf {2 \times\frac{22}{7} \times 35 \times h}$

➠ $\mathsf {2 \times\frac{22}{7} \times 35 \times 220}$

As, Lateral surface of cylinder = 2πrh

= 44000 cm²

Answer 2

$\blue{\bold{\underline{\underline{Given:-}}}}$

The base of a right circular cylinder = 220 CM.

The height of the cylinder = 2m =200cm.

$\green{\tt{\underline{\underline{To \: Find:-}}}}$

The lateral surface area of the cylinder.

$\orange{\bold{\underline{\underline{Step \:by\: step\:explanation:-}}}}$

Let the radius of the cylinder be $\red{\bold{\underline{\underline{r}}}}$ and height be $\red{\bold{\underline{\underline{h}}}}$ respectively.

A\Q,

$\implies \: 2πr = 220$

$\implies \: 2 \times \frac{22}{7} \times r = 220$

$\therefore \: r = 35.$

Now,

Lateral surface area of the cylinder = 2πr

$\large\underline\mathtt\color{gold}{Be brainly}$

$\implies \: 2 \times \frac{22}{7} \times 35 \times h$

$\implies \: 2 \times \frac{22}{7} \times 35 \times 220$

$\implies \: 44000 {cm}^{2}$
