C. 23.25 in.

(B)

Step-by-step explanation:

The circumference of a circle is the length of its perimeter, and it is given by the equation

where

r is the radius of the circle

In this problem, the radius of the circle is

Which is equivalent to

Therefore, substituting into the equation, we find the circumference of the circle:

So, option B.

step-by-step explanation:

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
