The area of the trapezoid is the product of the height and the average of the two bases:
<span>30 (25 + 33)/2 = 30 (58)/2 = 30 (29) = 870 square yd. </span>
<span>But we want to exclude the area of the fountain. </span>
<span>Since it's circular its area is π times the square of its radius, or 16π square yd. </span>
<span>So the area of the park, excluding the fountain, is </span>
<span>870 - 16π square yd, </span>
<span>or about 820 square yd.</span>

Determine the equilibrium solutions
We have:
To solve this, we first equate and to 0.
So, we have:
Factor out R in
Split
or
or
Factor out W in
Split
or
Solve for R
Make R the subject
When , we have:
Collect like terms
Solve for W
When , we have:
Collect like terms
Solve for R
So, we have:
When , we have:
So, we have:
Hence, the points of equilibrium are:
