4. Calculate the cost of constructing the drainage

The radius of a circular cricket ground is 14\(m\). A drainage 3\(m\) wide has to be constructed around the cricket ground for the purpose of draining the rainwater, then calculate the cost of constructing the drainage at the rate of \(₹\)192 per \(sq. m\).

 

The cost of constructing the drainage is \(₹\)\(56120\)\(55996\)\(56086\)\(56142\)
