Answer:
C = 98.3634m
Step-by-step explanation:
For finding out the Circumference of the circle first we should have radius an the formula of circumference of the circle is =2πr
As Area= πr²
and area is given as 770cm²
So Area= πr²
770 = πr²
770/π = r²
As π = 22/7 ≅ 3.1416
So putting value of π
So 770/3.1416 = r²
r² = 245.0980
Taking root on both sides
√r² = √245.0980
r = 15.655
So As Circumference of the circle is given as
C = 2πR
C=2(3.1416)(15.655)
C = 98.3634m
