Answer:
[tex]\boxed {\boxed {\sf r=\frac{c}{2\pi} }}[/tex]
Step-by-step explanation:
The formula for the circumference is:
[tex]c=2\pi r[/tex]
To solve for r, we must isolate r on one side of the equation by performing the inverse operation.
r is being multiplied by 2π. The inverse of multiplication is division. Divide both sides of the equation by 2π
[tex]\frac{c}{2\pi} =\frac{2 \pi r }{2 \ pi}[/tex]
[tex]\frac{c}{2\pi} =r[/tex]
The circumference formula solved for r is c/2π
