2. Calculate the total cost of cementing the floor

Mr Yadhav has a circular swimming pool. In which the floor radius of 15 \(m\) has to be cement at the rate of \(₹\) 20 per $m^2$. Then calculate the total cost of cementing the floor? [Use $\mathrm{\pi }$ \(= \)\(22/7\)]

 

The total cost of cementing the floor is\(₹\) .
