The area of the entire circle = pi r^2
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.
Answer:
x = 215
Step-by-step explanation:
15^2-13=x-3
225 - 13 = x - 3
212 + 3 = x - 3 + 3
215 = x
