Answer 1

Step-by-step explanation:

Given that:-

area of circle = 144π cm^2

.

we know that area of circle =

$\pi{r}^{2}$

so,

$\pi{r}^{2} = 144\pi {cm}^{2}$

${r}^{2} = 144$

$r = \sqrt{144 }$

r = 12.

.and we know that the, circumference of circle = 2πr

put the value:-

$circumference = 2 \times \frac{22}{7} \times 12 = 75.39$
