Question

The circle above has an area of 144 pi cm^2. What is the area of the blue sector? Use 3.14 for pi.

Answer 1

150.72 cm^2

Explanation:

The blue area has an angle of 120 degrees, and 120/360 = 1/3, which shows that the blue area is 1/3 of the circle. In that case, the blue area is just 144pi/3. That simplifies to 48 pi.

48*3.14 = 150.72
