Question

If the area of the circle below is 10 in2 what is the area of the shaded sector (The shaded area is 90 Degrees)

Answer 1

Answer:

A) Area of sector = 2.5 in².

Step-by-step explanation:

Given  : If the area of the circle below is 10 in².

To find : What is the area of the shaded sector .

Solution : We have given that

Area of the circle = 10 in².

Formula of area of circle = $\pi *r^{2}$.

$\pi *r^{2}$ = 10

$r^{2}$ = $\frac{10}{3.14}$

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

Plugging the values

Area of sector =  $\frac{90}{360}$* 10.

Area of sector = 2.5 in².

Therefore, A) Area of sector = 2.5 in².
