C
C'
= 12 and d' = 0.50?
A) 3
B) 6
C) 12
D) 24

Answer 1

Answer:

Step-by-step explanation:

we know that

The circumference of a circle is equal to

where

D is the diameter of the circle

In this problem we have

the circumference of the circle is

------> equation A

the circumference of the circle is

------> equation B

and the ratio of the circumference of the circle to the circumference of the circle is

------> equation C

Substitute the equation A and equation B in the equation C

Find the radius r'

therefore

the answer is  the option A
