Given a circle with measures of (C, d, and r) and a circle with measures of (C', d', and r'), find r' if C/C' = 0.25 and d = 6.0.

Respuesta :

Answer:

12, r' is 12

Step-by-step explanation:

c/c' = 0.25, so c' is 4 times as much as c, the second circle is 4 times  bigger than the first. So r' is 4r, we know that d = 6, and r is 1/2 of d, so r = 3, r' is 4r, so r' is 12
12, r’ is 12 hope this helps
