Estimate the area of a semi-circle with center (5,0) and radius 5 using the trapezoidal rule with 5 strips.

5. Semi-circle Area Estimation
The semi-circle has its center at $(5,0)$ and a radius of 5 units.
The equation of the semi-circle is $(x-5)^2 + y^2 = 5^2$, so $y = \sqrt{25 - (x-5)^2}$ for the upper semi-circle.
The x-range is from $x=0$ to $x=10$.
The width of each strip/rectangle is $h = \frac{10-0}{5} = 2$ units.
