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:

[tex]V = \frac{2 \pi }{T} * r [/tex]

We multiply both sides of = sign by T

T*V = 2*[tex] \pi [/tex]*r

Now we divide both sides with 2*[tex] \pi [/tex]

[tex] \frac{T*V}{2* \pi } =r[/tex]

which is now solved for r
