NettetThe question is: what does the integral with respect to r of πr 2 represent geometrically? Like you said, we know it's not a sphere. It would have to be a shape so that each two … NettetUse Green's Theorem to calculate the area of the disk D of radius r defined by x 2 + y 2 ≤ r 2. Solution: Since we know the area of the disk of radius r is π r 2, we better get π r 2 for our answer. The boundary of D is the circle of radius r. We can parametrized it in a counterclockwise orientation using c ( t) = ( r cos t, r sin t), 0 ≤ t ≤ 2 π.
