Answer:
The area of the circle is 314 in^2.
Step-by-step explanation:
10 inches is the radius.
The formula for the area of a circle is pi times radius squared.
So your equation would be: 
10^2 = 100
Then you do 
or 3.14 times 10 = 314.1592654 or just 314.

One way to solve this is to look at the size of the poster, and then subtract the size of the picture so you have the area that needs to be painted left.
Area of square poster - 3x × 3x = 9x^2
Area of painting - 2x × 2x = 4x^2
9x^2 - 4x^2 = 5x^2
The area is 5x^2
Answer:
From pair [2,4]
Y= 3x-2 x=2
Then y = 3[2] - 2 = 6-2 = 4
The equation [b]
