Well, if the diameter is 4 u, the radius is 2 u.
The formula for finding the circumference of a circle is 2*pi*r
In this case, we'd just plug in 2 for r.

Hi there!
We can solve by setting both equations equal to each other:
.5x + 4 = -.25x² + 5
Move everything to one side:
0 = -.25x² - .5x + 1
Multiply both sides by 4 to cancel out the decimals:
0 = -x² - 2x + 4
Factor out negative from both sides:
0 = x² + 2x - 4
Use the quadratic formula:
Plug in the corresponding terms:
Simplify:
Simplify the radical to reduce:
Divide all terms by 2:
