The formula for the circumference of a circle is C = 2(pi)r , where r is the radius of the circle. What is the formula when solved for r?
r = C/(2 * pi)
thank you :)
You're welcome.
To solve the formula C = 2(pi)r for r, we need to isolate r on one side of the equation.
Start by dividing both sides of the equation by 2(pi), like this:
C/(2(pi)) = r
Since r is the radius of the circle, the formula for r, when solved, is:
r = C/(2(pi))
So, the formula for the radius of a circle can be expressed as r = C/(2(pi)).
