Answer 2

Given :

Area of circle = 88

Find:

circumference of circle .

formulae used

circumference of circle =2πr

area if circle = πr²

circumference of circle = 2πr

88 = 2 × 22/7 × r

r = 88 × 7 /2 × 22 (dividing 88 by 22 )

r = 4 × 7 / 2 ( dividing 4 by 2 )

r = 2 × 7

r = 14 cm

Area of circle = πr²

Area of circle = 22/7 × (14)²

Area of circle = 22/7 × 196 ( dividing 196 by 7 )

Area of circle = 22 × 26

Area of circle = 616 sq.cm
