Question

find the circumference of a circle having the following area 616sqcm​

Answer 1

Answer:

according to question :-

area = 616

πr^2 = 616

22/7 * r^2 = 616

r^2 = 616 * 7/ 22 = 196

r^2 = 196

r = √196 = 14

r = 14

now

circumference = 2πr = 2*22*7 * 14 = 2*22*2 = 88

circumference = 88 cm

hope you understand plz thank my answer

Answer 2

Answer:

pie r ² = 616 cm²

r² = 616 / 3.1416

r² = 196

r = 14 cm

Than,

circumference of circle = 2pie r

2 * 3.1416 * 14 cm

= 87.96 cm answer
