Question

If the area of a sector of a circle is $\frac{5}{18}$th of the area of that circle, then the central angle of the sector is 100. Is it true or false?

• A. True
• B. False

Answer 1

The correct option is A True

For ${180}^{\circ }$, we have $\frac{1}{2}$ of the total area.

Hence, for ${\frac{5}{18}}^{th}$ of the total area, we have $360\times \frac{5}{18}={100}^{\circ }$
