Question

What is the approximate area of the shaded sector in the circle shown below?

Answer 1

Answer: C. $17.3\ in^2$

Step-by-step explanation:

The area of a sector with central angle x and radius r is given by :-

$A=\dfrac{x}{360^{\circ}}\times\pi r^2$

In the given picture, the radius of the circle = 3.7 in.

The central angle =$145^{\circ}$

Now, the area of the sector in the picture will be :-

$A=\dfrac{145^{\circ}}{360^{circ}}\times\pi (3.7)^2\approx 17.3\ in^2$

Hence, the approximate area of the shaded sector in the circle = $17.3\ in^2$
