Radius of Circular field = 7 m if Cost of ploughing at the rate of rs. 10 per meter square is Rs 1540

Step-by-step explanation:

Cost of ploughing at the rate of rs. 10 per meter square is Rs 1540

Area of field = 1540/10  = 154 m²

Field is circular

Radius of circular field = R m

Area of field  = πR² m²

π = 22/7

πR² = 154

=> (22/7) R² = 154

=> R² / 7 = 7

=> R² = 7 * 7

=> R² = 7²

=> R = 7

Radius of Circular field = 7 m
