Question

solve this one pls pls

Answer 1

Area of circle=616
Πr²=616
r²=196
r=14
C=2Πr
=2×22/7×14=88cm
similarly
circumference of 2nd one is 132cm

Answer 2

Hi mate

Here is ur answer ⬇️⬇️⬇️⬇️

i) 616
πr^2=616
3.14 × r^2 = 616
r^2 = 196.178
r= 14.006=14

circumference = 2πr = 2×3.14×14= 87.92 units

ii) 1386
πr^2=1386
3.14×r^2=1386
r^2=441.40
r= 21.009=21

circumference=2πr=2×3.14×21=131.88 units

I hope this will help you
