Question

Circle A is shown with a central angle marked 42 degrees and the radius marked 8 inches.

Answer 1

Answer:

D.  $\pi (8in)^{2}\times \frac{42}{360}$

Step-by-step explanation:

We are given that,

Radius of the circle = 8 inches

Central angle of the circle = 42°

As, we know,

Area of a sector of a circle = $\pi r^{2}\times \frac{\theta}{360}$

So, substituting the values, we get,

Area of a sector the circle = $\pi 8^{2}\times \frac{42}{360}$

Thus, option D i.e. $\pi (8in)^{2}\times \frac{42}{360}$ can be used to find the area of the sector.
