The formula for area of a circle is (pi)*radius^2
Radius is half of diameter so the radius is 2.
2 squared is 4, then multiply by pi to get an answer of 4(pi) or 12.56.
-x - y = -5
y = x + 1
-x -(x + 1) = -5
-x - x - 1 = -5
-2x = -5 + 1
-2x = -4
x = -4/-2
x = 2
y = x + 1
y = 2 + 1
y = 3
solution is : (2,3)
