Question

The radius of a circle is 4 miles. What is the area of a sector bounded by a 180 arc?

Answer 1

Answer:

The area of sector is $25.12 miles^2$

Step-by-step explanation:

Radius of circle = 4 miles

We are supposed to find the area of a sector bounded by a 180 arc

$\theta = 180^{\circ}$

Area of sector =$\frac{\theta}{360^{\circ}} \pi r^2$

Area of sector = $\frac{180^{\circ}}{360^{\circ}} \times \frac{22}{7} \times 4^2$

Area of sector = $25.12 miles^2$

Hence The area of sector is $25.12 miles^2$
