Respuesta :
The answer is 30 CM.
Circumference is pi× diameter
So the diameter is 60.
1/2 of diameter is radius
60÷2= 30
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:
[tex]C = 2 \pi r[/tex] .....[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;
[tex]60 \pi = 2 \pi \cdot r[/tex]
Divide both sides by [tex]2 \pi[/tex] we have;
30 = r
or
r = 30 cm
Therefore, the radius of the circle is, 30 cm
