When they say to solve for a variable, they want you to isolate/get the variable by itself.


5.) Solve for b (get b by itself)

A=\frac{1}{2}bh   Multiply 2 on both sides to get rid of the 1/2

2A = bh        Divide h on both sides

\frac{2A}{h} =b


6.) Solve for r

C=2\pi r      Divide 2 and \pi on both sides

\frac{C}{2\pi } =r
