Answer:
The value of r from the provided formula is \(\frac{C}{2\pi} =r\).
Step-by-step explanation:
Consider the provided formula.
\(C = 2\pi r\)
Where r is radius of a circle and C is circumference.
Now solve the formula for r.
Isolate the variable r by dividing 2π from both side.
\(\frac{C}{2\pi} =\frac{2\pi r}{2\pi}\)
\(\frac{C}{2\pi} =r\)
Thus, the value of r from the provided formula is \(\frac{C}{2\pi} =r\).
