Answered by zarvis

we know that area of circle,=πr2
area=616decimeter
r2=616×7/22
r2=196
taking square root
r=+(-)14
but radius will not be negative so r=14
Proud to help you

anokhiannupall6g: thanks

Answered by sakhti

area of circle =
$\pi {r}^{2}$
area = 616sqdecimeter (given)
${r}^{2} = 616 \div \pi$
r × r = 616 × 7 ÷ 22
= 4312 ÷22 = 196
r =
$\sqrt{196 } = 14$
