Question

1. malcom used a compass to draw a circle with a radius of 3 inches.

a. find the diameter of the circle.
b. estimate find the circumference of the circle. round the answer to the nearest inch. (use 3.14 for π.)

Explanation:

Step1: Find the diameter

The formula for the diameter \(d\) of a circle is \(d = 2r\), where \(r\) is the radius. Given \(r=3\) inches.
\(d = 2\times3\)

Step2: Find the circumference

The formula for the circumference \(C\) of a circle is \(C=\pi d\). We know \(d = 6\) inches (from step 1) and \(\pi = 3.14\).
\(C=3.14\times6\)

Answer:

a. \(6\) inches
b. \(19\) inches
