Question

circumference of an circle is 308cm then what would be the area would be​

Answer 1

$\huge\mathfrak{\red{Answer}}$

Area= 7546cm^2

Explanation:

Given that circumference of the circle is 308cm

$= > 2 \times \pi \times r = 308cm$

because circumference of circle =2πr

$= > \: 2 \times \frac{22}{7} \times r = 308$

$= > \: \frac{44}{7} r = 308$

$= > r = \frac{308 \times 7}{44}$

$= > r = 49$

Now,

$area \: of \: circle = \pi \times {r}^{2}$

Therefore,

area of the circle:-

$= \frac{22}{7} \times 49 \times 49$

$= 22 \times 49 \times 7$

$= 7546 {cm}^{2}$
