Answer:

C) 45.53in cubed.

Step-by-step explanation:

One formula for finding circumference is C=r2(pi).

So, if you plug in the numbers,

= C=7.25(2)(3.14)

= C=14.5(3.14)

= C=45.53

So, the answer is 45.53in cubed after multiplying all of the numbers.

Hope this helps :)

(I'm not sure if it's right though because the answer is cubed.)
