Quizplus · Accepted Answer

The length of the driveway, which is a semicircle, can be found using the formula for the circumference of a circle, $C = \pi d$, but since it's a semicircle, we use $\frac{1}{2} \pi d$. Substituting $\pi = 3.14$ and $d = 70$ ft, we get $\frac{1}{2} \times 3.14 \times 70 = 109.9$ ft.
