Question:

What is the Area of Sector GPH?

The area of the entire circle = pi r^2

The shaded area is equal to 9*pi

Step-by-step explanation:

The area of the shaded area = (40/360) * pi r^2

r = 9 cm

Area of the shaded area = 1/9 * 3.14 * 9^2

Area of the shaded area = 3.14 * 9

Area of the shaded area = 28.26

Notice one of the 9s disappeared. Where did it go?

You could begin the problem by writing out 9^2

Area = 1/9 * 3.14 * 9 * 9 Notice that 1/9 will cancel out 1 of the nines.

28.26 yds = Shaded area.

Note to Self:

The shaded area is equal to 9*pi
