ar. of cirlce = pie * r sq.
22/7 * r sq. = 98.56
r sq. = 98.56*7/22
r sq. = 689.92/22
r sq. = 31.36
r = under root 31.36
r = 5.6 cm
22/7 * r sq. = 98.56
r sq. = 98.56*7/22
r sq. = 689.92/22
r sq. = 31.36
r = under root 31.36
r = 5.6 cm

total surface area of circle = πr²
98.56 = 22/7 r²
r² = 98.56/22/7 = 98.56×7/22
r² = 31.36
r= 5.6 cm
98.56 = 22/7 r²
r² = 98.56/22/7 = 98.56×7/22
r² = 31.36
r= 5.6 cm
