Area of Circle = πr^2
3850 = (22 / 7 ) × r^2
(3850 × 7) / 22 = r^2
22950/22 = r^2
1225 = r^2
√1225 = r
35 = r
Circumference of Circle = 2 πr = 2 ×( 22/7) × 35
= 2 × 110 = 220
3850 = (22 / 7 ) × r^2
(3850 × 7) / 22 = r^2
22950/22 = r^2
1225 = r^2
√1225 = r
35 = r
Circumference of Circle = 2 πr = 2 ×( 22/7) × 35
= 2 × 110 = 220
