The sector of a circle with a diameter of 20 inches has a central angle measure of 36°. What is the area of the sector?

40π in²

10π in²

2π in²

π in²

plz explain what you did to get the answer so that i vcan understand and do it alone in the future

Respuesta :

We need the radius to find the area of sector.

radius = 20/2 = 10

Area of sector:

πr²(x/360) = x is the central angle in degrees.
π(10)²(36/360)
10π in²

Hope this helps :)
