Question

find the circumference of the circle whose area is 616 CM square​

Answer 1

Answer:

88cm

Step-by-step explanation:

the area of circle is πr*r Square = 616

22/7*r*r=616

r*r=616/22*7=196

by talking square root r=14

for circumference =2*π*r

=2*22/7*14=88cm

Answer 2

Answer:

$\begin{gathered}\begin{gathered} \sf \: \pi {r}^{2} = 616 \\ \\ \sf \: {r}^{2} = \frac{616 \times 7}{22} \\ \ \\ \sf\: {r}^{2} = 28\times 7 \\ \\ \sf \: r = 14 \\ \\ \sf \: Circumference = 2\pi r = 2 \times \frac{22}{7} \times 14 = 88cm \\ \\ \sf \: Circumference_{(Circle)} \blue{=88cm}\end{gathered}\end{gathered}$
