The length of an arc, s, of a circle with radius r and angle-measure m (in radians) can be written by the formula %0D%0A%0D%0A2%0D%0A%0D%0A%0D%0A=%0D%0A%0D%0A2%0D%0A%0D%0A. Solve for r.

Answer 1

To solve for r, we need to rearrange the formula. We can start by writing the given formula:

s = r * m

Now, let's isolate r. We can divide both sides of the equation by m:

s/m = r

Therefore, the formula to solve for r is:

r = s/m
