Given:-
Circumference of circle = 96.8 m
Circumference of circle = 2πr
96.8 = 2*22/7*r
r = 96.8*7/2*22
r = 15.4 m
Area of circle = πr²
= 22/7*15.4*15.4
= 745.36 m² Ans.
Ans.) Its area is 745.36 m².

Circumference= 2×π×r
=2×22÷7×X
(X is the radius)
96.8 = 44 ÷ 7×X
96.8 = 6.28×X
96.8 ÷ 6.28 = X
15.4 = X
Therefore radius = 15.4m
Area = π×r×r
= 22÷7 × 15.4 × 15.4
= 3.14 × 237.16
= 759.79m square
*Sry I was not able to put the square above the number...☺
