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 formula for the circumference of a circle

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter. We can approximate \( \pi \) as \( \frac{22}{7} \) for this problem.

Step2: Solve for the diameter \( d \)

We know that \( C = 44 \) inches and \( C=\pi d \). Substituting \( \pi=\frac{22}{7} \) into the formula, we get \( 44=\frac{22}{7}\times d \). To solve for \( d \), we can rearrange the formula: \( d=\frac{44\times7}{22} \).

Step3: Calculate the value of \( d \)

Simplify the expression \( \frac{44\times7}{22} \). First, \( 44\div22 = 2 \), then \( 2\times7=14 \). So \( d = 14 \) inches.

Answer:

14 in.
