Question

the area ofa circle is 6.616m^2find its circumference​

Answer 1

Answer:

Given, Area a = 6.616 m^2

Radius r = to find

Circumference s = to find

Now,

$a = \pi {r}^{2} \\ {r}^{2} = \frac{a}{\pi} = \frac{6.616}{3.141} = 2.106 \\ r = \sqrt{2.106} \\ r = 1.451 \: m \\ \\ \\ so \: \: s = 2 \: \pi \: r \\ = 2 \times 3.141 \times 1.451 \\ = 9.115 \: m \\ = answer$
