Answer 1

Given:

The area of a semicircle is 0.7693 square centimeters.

Explanation:

To find the radius:

Using the area of a semicircle formula,

$\begin{gathered} A=\frac{\pi r^2}{2} \\ 0.7693=\frac{3.14\times r^2}{2} \\ r^2=\frac{0.7693\times2}{3.14} \\ r^2=0.49 \\ r=\sqrt[]{0.49} \\ r=0.7 \end{gathered}$

Thus, the radius of the semicircle is 0.7 cm.
