Use double integral to find the volume of the cylinder-like object that exists above the first quadrant on the xy plane and below the plane z = 15. The cross section of this "cylinder" on the xy plane is given by the polar equation r = 5 sin (20) (shown in figure, ignore the scale/numbers). Use the formula Volume= ff zdA, R where R is the domain over which we are interested to find the volume under the surface z. Sketch the region R before doing the integration. (In polar coordinates, dA = rdrde)
