Answer 2

Answer:

Area of the circle is $1386 \mathrm{~cm}^{2}$

Step-by-step explanation:

Given:

The circumference of a circle $=132 \mathrm{~cm}$

Formula used:

Circumference$(C)$ of a circle $=2 \pi r$

Area of a circle$=\pi r^{2}$

Where, $r$ = radius

Calculation:

According to the question,

$\begin{aligned}&C=2 \times 22 / 7 \times r \\&\Rightarrow 132=44 \mathrm{r} / 7 \\&r=21 \mathrm{~cm}\end{aligned}$

Now,

Area of a circle $=\pi r^{2}$

$\Rightarrow 22 / 7 \times 21 \times 21=1386 \mathrm{~cm}^{2}$

$\therefore$ The area of circle is $1386 \mathrm{~cm}^{2}$.
