Answer:

The second choice.

Step-by-step explanation:

A central angle is one whose vertex is at the center of a circle and whose endpoints are on the outer edge of the circle.

The only figure we have with a central angle in it is the second one.

What is the area of a sector of a circle with a radius of 9 centimeters and formed by a central angle that measures 120°?
LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

If this was an entire circle, the area could be found by using

Area = pi * r^2 where r = 9

To take the central angle into account, use this formula

Area = 120/360  * pi * r^2

Area = 1/3 * pi * 9^2

Area = 27 pi

area  = 84.78 cm^2  which isn't there.
