Answer 1

$v \: = \: \frac{2\pir}{t}$

In Physics, Uniform Circular Motion is used to describe the motion of an object traveling at a constant speed in a circle. The speed of the object, also called tangential velocity, can be calculated using the formula above. Here, r represents the radius of the circle, T the time it takes for the object to make one complete revolution, called a period.
