Final answer:

To find the circumference of a circle with a radius of 7 inches, we use the formula C = 2πr, which gives us a result of approximately 43.98 inches. Rounding this to the nearest inch, the circumference is 44 inches, making option B the correct answer.

Step-by-step explanation:

The circumference of a circle is calculated using the formula C = 2πr, where π (pi) is approximately 3.14159 and r is the radius of the circle. Given a radius of 7 inches, we substitute that into the formula to get:

C = 2 * 3.14159 * 7 in

C = 43.98226 in

Rounding to the nearest inch gives us a circumference of 44 inches. Therefore, the correct answer is B. 44 in.
