in uniform circular motion, the speed v of point on the edge of a spinning disk is v=2π/T times r. where r is the radius of the disk and T is the time it takes the point to travel once around the circle. Solve the formula for r.

First lets write down starting formula:

\(V = \frac{2 \pi }{T} * r\)

We multiply both sides of = sign by T

TV = 2\(\pi\)r

Now we divide both sides with 2\(\pi\)

\(\frac{T*V}{2* \pi } =r\)

which is now solved for r
