Answer the given questions about the indicated examples of this section.

In the first line of Example 2, if “diameter” is changed to “radius,” what are the results?

**Data from Example 2**

A circular oil spill has a diameter of 2.4 km. It is to be enclosed within special flexible tubing. What is the area of the spill, and how long must the tubing be? See Fig. 2.79. Since d = 2r, r = d / 2 = 1.2 km. Using Eq. (2.10), the area is

The length of tubing needed is the circumference of the circle. Therefore,

**Transcribed Image Text:**

## A = πr² = TT (1.2) ² = 4.5 km²
