A builder is installing a norman window made up of a rectangle topped by a semicircle. If the radius of the semicircle is r, and

the rectangle is 3r high, find the area of the window as a function of r.
Please help, this question is driving me insane!

F(r)= (π*r^2)/2 + 3r

Basically, when they say find the area as a function, they want you to make an equation so the answer will stay proportional based on what the variable (in this case r) equals. So, in the equation I gave you, if you find the value of r, you have the answer. But, since we do not have the value of r, we must simply create a function based on the data we do have...I hoped this helped you:)
