Yes if they have there sirens on that is
CALCULATOR PART
1. The area of R + S is unsigned, meaning you want to find
where ![[a,b]](https://tex.z-dn.net/?f=%5Ba%2Cb%5D)
is the interval between the leftmost and rightmost intersections of 
and 
.
First use your calculator to find these intersections:
so that 
and 
. Now compute the integral using your calculator:
2. The volume, using the washer method, is given by the integral
3. A circle of radius 
has area 
; a semicircle with the same radius thus has area 
. Each cross section of this solid is a semicircle whose diameter is the vertical distance between 
and 
, or 
. In terms of the diameter 
, the area of each semicircle would be 
. Then the volume of the solid is
NON-CALCULATOR PART
4. The mean value theorem says that for a function 
continuous on an interval and differentiable on 
, there is some 
such that
If this happens to be an antiderivative of , then we end up with
is continuous and differentiable everywhere, so the MVT applies. We have 
, so the MVT tells us there is some 
such that
That is, the average value of on ![[0,\pi]](https://tex.z-dn.net/?f=%5B0%2C%5Cpi%5D)
is 0. The MVT says there is some 
in the interval such that the function takes on the average value itself; this happens for 
.
