The speed of an object in uniform circular motion is equal to two times pi (I like pi) times the radius divided by the period of the circle.

|
The centripetal acceleration is equal to the object's speed squared divided by the radius.
|

|
|
The centripetal force is equal to the mass times the velocity squared divided by the radius.

|
The tangent of the angel of the incline is equal to the velocity squared divided by the radius times the acceleration due to gravity.

|
The velocity squared of an object in orbit around the earth is equal to the gravitational constant times the mass of the earth divided by the distance from the enter of the earth to the center of the object.
