We will have the following:
Radius: We can see that the radius is 4 ft. [Marked]
Area of the base: We recall that the area of a circle will be given by:

So:

So, the area is approximately 50.27 ft^2.
Volume of the cylinder: We recall that the volume of the cylinder is given by:

So:

So, the volume is approximately 150.80 ft^3.
