Question

circle o has a circumference of approximately 44 in. what is the approximate length of the diameter, d? 7 in 14 in 22 in 44 in

Explanation:

Step1: Recall the circumference formula

The formula for the circumference of a circle is $C = \pi d$, where $C$ is the circumference and $d$ is the diameter.

Step2: Solve for the diameter

We know $C\approx44$ in and $\pi\approx\frac{22}{7}$. Rearranging the formula $C = \pi d$ for $d$ gives $d=\frac{C}{\pi}$. Substituting the values, we have $d=\frac{44}{\frac{22}{7}}$.

Step3: Calculate the value of the diameter

$d = 44\times\frac{7}{22}=14$ in.

Answer:

14 in
