Find the area of the shaded region.
Citrus2011 [14]

Answer:

pi × 18cm^2

Or approximately,

56.52cm^2 (using 3.14 for pi)

or

56.5487cm^2 (using pi button on calculator)

Step-by-step explanation:

Area of a circle is pi times [radius squared].

All circles are 360°.

Problem can be solved by finding area of whole circle, and then using ratios.

Whole Circle: area = pi × (9cm)^2 = pi × 81cm^2

80° / 360° = Area[shaded] / (pi × 81cm^2)

pi × 18cm^2 = Area[shaded]

((If you read my answer before the edit, I am sorry. I made a calculator error.))

X + y = 3 <br>-2x + 4y = 6
Finger [1]
I'm assuming this is a system of equations you want solved so,

x = -y + 3

-2(-y+3)+4y = 6
2y - 6 + 4y = 6
6y = 12
y = 2

x + 2 = 3
x = -1

(-1,2)
