Answer:
The correct option is 10....
Step-by-step explanation:
The formula of circumference of the circle is:
C = 2πr
where C is the circumference of the circle
r = radius
In this question we have given the circumference and we have to find out the radius:
Thus substitute the values in the formula:
C = 2πr
20π= 2πr
Move 2π to the L.H.S.
20π/2π = r
Cancel out π by π and 20/2 by the table of 2
Therefore we have:
10=r
Thus the correct option is 10....
