Question

The areas of the major and the minor sector of a circle are equal when the central angle is .

• A. ${90}^{\circ }$
• B. ${180}^{\circ }$
• C. ${60}^{\circ }$

Answer 1

The correct option is B ${180}^{\circ }$

When the central angle is equal to ${180}^{\circ }$, the areas of the major and minor sector is the same. In this case, we get two semi-circles of the same area.
