To solve an equation, we need to use inverse operations.
For C=2πr, the rr is being multiplied by 2π. To solve for r we would then need to divide both sides by 2π since division is the inverse operation of multiplication.
Dividing both sides of C=2πr by 2π gives C2π=2πr2π.
Simplifying then gives C. r=C2π.

The formula we are given is:
C=2πr
where C is the circumference of a circle and r is its radius.
To solve for r, we can isolate r on one side of the equation by dividing both sides by 2π. This gives:
C2π=2πr2π
Simplifying the right-hand side, we get:
C2π=r
Therefore, the solution for r is:
r=C2π

Result:
C2π
Explanation:
The given formula is:
C=2πr
We need to solve for r.
Dividing both sides of the equation by 2π, we get:
C2π=2πr2π
Simplifying the right-hand side, we get:
C2π=r
Therefore, the solution for r is:
r=C2π
