S=2\pi r\times 16
Add 6 and 10 to get 16.
S=32\pi r
Multiply 2 and 16 to get 32.
S=2\pi r\times 16
Add 6 and 10 to get 16.
S=32\pi r
Multiply 2 and 16 to get 32.
32\pi r=S
Swap sides so that all variable terms are on the left hand side.
\frac{32\pi r}{32\pi }=\frac{S}{32\pi }
Divide both sides by 32\pi .
r=\frac{S}{32\pi }
Dividing by 32\pi undoes the multiplication by 32\pi .
