78.46
Area of a cicle in terms of radius:
Area = π . r2 = 3.14 × 52 = 78.46 square inches.
In terms of diameter:
Area = π . (d/2)2 = 3.14 × (10/2)2 = 3.14 × (5)2 = 78.46 square inches.
In terms of circumference:
Area = C2/(4π) = 31.42/4π = 985.96/(4 × 3.14) = 985.96/(12.56) = 78.46 square inches.

Circumference of a circle=31.4
circumference of circle=2πr
31.4=2*22/7*r
31.4*7/2*22=r
4.9=r
area of circle=
πr²=22/7*(4.9)²=75.46squnits
