Area of circle = 301.84 cm
Let the radius = r cm
circumference of circle =πr²
πr² = 301.84
22/7 *r² = 301 .84
r² = 301.84 * 7 / 22
= ( √7*7)^1/2 * 13.75
r = √13.72 *7
r=√7*7 *1.96
r= 7*14
r= 9.8 cm
Radius = 9.8cm
circumference = 2*22/7 *9.8
44*1.4
= 61.6 cm
Let the radius = r cm
circumference of circle =πr²
πr² = 301.84
22/7 *r² = 301 .84
r² = 301.84 * 7 / 22
= ( √7*7)^1/2 * 13.75
r = √13.72 *7
r=√7*7 *1.96
r= 7*14
r= 9.8 cm
Radius = 9.8cm
circumference = 2*22/7 *9.8
44*1.4
= 61.6 cm
