Answer:
Area: 96 x pi
Perimeter: 8 x pi
Step-by-step explanation:
Area: the shaded part is 1/3 of the circle and is 120 degrees of the 360 degrees of the circle
use the area formula: r^2 x pi x 120/360
plug in r=12 and you should get 96 pi
Perimeter: the formula for circumference is 2 x pi x r x 120/360
plug in r=12 and you should get 8 x pi
