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 \(d\)

Given \(C = 44\) in and taking \(\pi\approx\frac{22}{7}\).
From \(C=\pi d\), we can express \(d=\frac{C}{\pi}\).
Substitute \(C = 44\) and \(\pi=\frac{22}{7}\) into the formula: \(d=\frac{44}{\frac{22}{7}}\).
Using the rule for dividing by a fraction (\(a\div\frac{b}{c}=a\times\frac{c}{b}\)), we have \(d = 44\times\frac{7}{22}\).
\(44\div22 = 2\), so \(d=2\times7=14\) in.

Answer:

14 in.
