Distance covered by an object
=========================
d
= Circumference of a circle
= 2 × Pie × r
= 2 × 3.14 × 1
= 2 × 3.14
= 6.28 meters
Time taken to complete one round
= t = 10 seconds
Speed of an Object
= Distance covered / time taken
v = d / t = 6.28 / 10 = 0.628 m / s
Thus speed of the object = 0.628 m /s

Answer:
Radius=1m
Time=10sec.
Speed= ?
Formula of finding speed,
speed= pieR^2/t
= 22/7×1×1/10
= 22/7/10
= 22/7×1/10
= 2.2/7
= 0.211
