Question

Find the area and permeter of the shaded region of the circle:

Answer 1

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
