341 Example 1Finding the Circumference of a Circle A circle has a diameter of 4.5 ft, as shown in Figure 2. Find its circumference, using 3.14for p. If your calculator has a key, use that key instead of a decimal approximationfor p.p The circumference of a circle is the distance around that circle.
