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.
Which is the shape of the region being integrated?
radius, or base and height =
(If you are entering a base and height, enter them separated
by a comma, e.g., 4, 3)
area =
