question 10 of 10
what angle measure does a semicircle have?
a. 180°
b. 360°
c. 90°

Explanation:

Step1: Recall the total angle of a full circle

A full - circle has an angle measure of \(360^{\circ}\).

Step2: Calculate the angle measure of a semicircle

A semicircle is half of a full - circle. So, we use the formula \(\theta=\frac{360^{\circ}}{2}\).

$$ \theta = 180^{\circ} $$

Answer:

A. \(180^{\circ}\)
