Circle O has a circumference of approximately 44 inches.

What is the approximate length of the diameter?

A. 7 inches
B. 14 inches
C. 22 inches
D. 44 inches

Answer :

The circumference of a circle is related to its diameter by the formula

$$
C = \pi d.
$$

Given that the circumference is approximately 44 inches, we can solve for the diameter $d$ by rearranging the formula:

$$
d = \frac{C}{\pi}.
$$

Substituting $C = 44$ inches gives

$$
d \approx \frac{44}{\pi} \approx 14.0056 \text{ inches}.
$$

Rounding to the nearest whole number, we find that the diameter is approximately 14 inches.

Thus, the approximate length of the diameter is $\boxed{14 \text{ in.}}$
