Question

Solve for r: C = 2(pi)r.

Answer 1

divide both sides by \[2 \pi\]

Answer 2

theres no number on both sides how would that work ?

Answer 3

to solve for r, you have to isolate it by itself. it does't matter whether there is a number or not.

Answer 4

ok so 2(3.14)r ? and i do it again for c ?

Answer 5

\[C=2\pi r\]; to solve for r, isolate it by dividing both sides with...
\[C \div 2\pi=2\pi r \div 2\pi\]

Answer 6

so would it be r=c/(pi)

Answer 7

don't forget the 2
