Question

Find the circumference and area of a circle of radius 12cm

Answer 1

$\textbf{\underline {\underline {Solution:-}}}$

Circumference :-

$2\pi \: r = 2 \times \frac{22}{7} \times 12$

$: \implies {75.42}$

Now area :-

$\pi{r}^{2}$= $\frac{22}{7} \times 12\times 12$

$: \implies {452sq}$

Answer 2

Step-by-step explanation:

perimeter=2πr=2*22/7*12

=I am writing in

44*12/7 =75.4cm

area=πr2=3.14*12*12

=452.16cm.sq

hope the answer is correct.
