50.2=2(3.14r)
We move all terms to the left:
50.2-(2(3.14r))=0
We add all the numbers together, and all the variables
-(2(+3.14r))+50.2=0
We calculate terms in parentheses: -(2(+3.14r)), so:We move all terms containing r to the left, all other terms to the right
2(+3.14r)
We multiply parentheses
6r
Back to the equation:
-(6r)
-6r=-50.2
r=-50.2/-6
r=8+1/2.72727272727
