Question

Find radius of circle area of circular ground is 3850 sq. M

Answer 1

area of circle=pi r^

 thererefore, 3850 =22÷7 ×r^

 therefore, r2 = 3850 ×7÷ 22

                        =1225

Answer 2

Area of circle=πr^2

3850=22/7 × r^2

r^2 = 3850×7/22

r^2 = 26950/22

r^2= 1225

r= √1225

r=35m
