Circumference = 2 x 3.14 x radius
295.16 = 6.28 x radius
295.16 / 6.28 = radius
47 = radius
A) 12 and -9
12 + (-9) = 3
12 - (-9) = 21
.
b) i think there is no right answer here ?
:)
They result in the same equation
rewrite it:
2y = 4x +18
3y = 6x + 27
divide so that you have only y
y = 2x + 9
y = 2x + 9
