Answer:
C
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
(central angle is equal to the measure of the arc, that is 30° )
A = πr² × [tex]\frac{30}{360}[/tex]
= π × 12² × [tex]\frac{1}{12}[/tex]
= 144π ÷ 12
= 12π
≈ 37.7 cm² ( to the nearest tenth )
