Area of circle = pie * r * r
Area give 3850 sq m
So 22/7 * r * r = 3850
r * r = (3850 * 7) / 22
r * r = 1225
r = 35 m

Answer:
radius of the circular ground = 35 cm
Step-by-step explanation:
Area of a circular ground is 3850 sq m. Find the radius of the circular ground.
Area of a circular field = π R²
π = 22/7 a constant
R = Radius of circular filed
Area = 3850 cm² given
=> (22/7) R² = 3850
=> R² = 3850 * 7 /22
=> R² = 175 * 7
=> R² = 25 * 7 * 7
=> R² = 5 * 5 * 7 * &
=> R² = (5 * 7)²
Square rooting both sides
R = 5 * 7 = 35 cm
radius of the circular ground = 35 cm
