Answer

\frac{1}{2} \pi r^2$.

Welcome back Ntsako — missed you this week.

2.1.1 The area of a semi-circle is given by the formula $A = \frac{1}{2} \pi r^2$ . We are given that the area of one shooting circle is $107.17 m^2$ and $\pi = 3.14$ . We need to show that the radius $r$ is $9 \text{ m}$ .

Step 1: Substitute the given area and $\pi$ value into the formula to solve for $r$ . $107.17 = \frac{1}{2} \times 3.14 \times r^2$

Step 2: Multiply both sides by
