Question 914433: Hello,
My name is Jeremy and I am having a problem with my take home quiz. I think I am doing it right but I am not for sure and I really to get a 100% on this one.
Here is the question:
You have 100 ft of fencing and you are in charge of enclosing a region that has the
shape shown in the picture below. The region is made of a rectangle and two semicircles.
Write a function that calculates the area of the region as a function of the
length of the rectangle.
I tried this:
P=100
100=2(pi)r + 2r + 2x or 50=(pi)r + r +x
Then solve for x= -(pi)r - r + 50
The substitute to and solve and get:
A= -(pi)r^2 + 98r
is this right?
thank you.
