The formula to find the area of a circle:
, where
is the radius.
The formula to find the circumference (perimeter) of a circle:
, where
is the radius.
1) To find the circumference of the circle, we need to find the radius (
) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.
Cancel the
by bringing it to the other side.
÷ 

2) Find the circumference of the circle by using the formula,
.
= 
=
in
f(x) -g(x) = -3x-5 -(4x-2)
distribute
-3x-5 -4x+2
combine like terms
-7x-3
Answer:
-7x-3
1/2 can't be rounded so its 1/2 still.
