Answer:
The radius of the circle is cm.
Step-by-step explanation:
In context to the question asked,
We have to find the radius of a circle,
As per data given in the question,
We have,
Circumference = cm
For calculating radius,
The formula to be used for,
Circumference =
By substituting the values,
Expressing as a single fraction,
Multiply and to get ,
Swap sides so that all variable terms are on the left-hand side.
Multiply both sides by , the reciprocal of .
Multiply and to get ,
Hence radius of the circle is cm.
