Each of the following integrals represents the area of either a triangle or part of a circle, and the variable of integration measures a distance. In each case, say which shape is represented, and give the radius of the circle or base and height of the triangle. You will find it useful to make a sketch of the region, showing the slice used to find the integral, labeling the variable and differential on your sketch. Then evaluate the integral to find the area.
A. ∫₀√¹⁵ √15 - h² dh
Which is the shape of the region being integrated?
A. Triangle
