1.133.54=2(3.14)r
We move all terms to the left:
1.133.54-(2(3.14)r)=0
We add all the numbers together, and all the variables
-(2(3.14)r)+0.61182=0
We calculate terms in parentheses: -(2(3.14)r), so:We add all the numbers together, and all the variables
2(3.14)r
We multiply parentheses
6.28r
Back to the equation:
-(6.28r)
-(+6.28r)+0.61182=0
We get rid of parentheses
-6.28r+0.61182=0
We move all terms containing r to the left, all other terms to the right
-6.28r=-0.61182
r=-0.61182/-6.28
r=0.61182/6.28
