Verified Answer :

Answer:

Volume of cylinder, \(V=87.42\ m^3\)

Step-by-step explanation:

It is given that,

Area of the base of a cylinder, \(A=28.2\ m^2\)

Height of the cylinder, h = 31. m

We need to find the volume of the cylinder. The volume of a cylinder is given by the formula as :

\(V=\pi r^2 h\)

Where, \(A=\pi r^2\) is the area of the base of cylinder

\(V=A\times h\)

\(V=28.2\times 3.1\)

\(V=87.42\ m^3\)

So, the volume of the cylinder is \(V=87.42\ m^3\). Hence, this is the required solution.
