Verified Answer :

The answer is 30 CM.
Circumference is pi× diameter
So the diameter is 60.
1/2 of diameter is radius
60÷2= 30

Answer:

Option 4th is correct

radius of the circle is, 30 cm

Step-by-step explanation:

Circumference of the circle(C) is given by:

\(C = 2 \pi r\)         .....[1]

where,

r is the radius of the circle.

As per the statement:

The circumference of a circle is 60π cm

⇒C = 60π cm

Substitute this value in [1] we have;

\(60 \pi = 2 \pi \cdot r\)

Divide both sides by \(2 \pi\) we have;

30 = r

or

r = 30 cm

Therefore, the radius of the circle is, 30 cm
