What are the linear velocity, period and angular velocity of an object moving in a circle with a radius of 20m for 100m within 10s?

What are the linear velocity, period and angular velocity of an object moving in a circle with a radius of 20m for 100m within 10s?

Linear velocity = 100 / 10 = 10m / S
Angular velocity = linear velocity / radius = 10 / 20 = 0.5rad/s
Period = perimeter / linear velocity = 20 * π * 2 / 10 = 4 π s
This is not specific enough
It's all a direct set of formulas. How can we be more specific
