Answer:

45.24 cm

Step-by-step explanation:

C = pi(d)

Since we have our radius, we can find our diameter. To get the diameter, we multiply the radius by 2. In this case; 7.2 cm.

7.2(2) = 14.4

Then, we multiply the diameter by pi.

(pi)(14.4) = 45.238

45.238 ---> 45.24

The answer that I got was also 45.24 cm
