Question

a circle has a diameter of 23 units. what is the circumference? use 3.14 as an approximation for π. units

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute values

Given \( d = 23 \) and \( \pi \approx 3.14 \), substitute into the formula: \( C = 3.14 \times 23 \).

Step3: Calculate the product

\( 3.14 \times 23 = 72.22 \).

Answer:

72.22
