Area of circle=πr^2
=(22/7)×10.5×10.5
=22×110.25÷7
=346.5cm square
Cost
=346.5×150

Given Radius of the circle ( r ) = 10.5m
Area of circular ground ( A ) = πr²
= ( 22/7 ) × ( 10.5 )²
= ( 22/7 ) × 10.5 × 10.5
= 346.5 m²
Now ,
cost of fill up the 1 sq m ground = Rs150
cost of fill up the 346.5 m² ground
= 150 × 346.5
= Rs 51925
