Question

the area of a circle is 28.26 square kilometers. what is the circles diameter?
round your answer to the nearest hundredth.
kilometers

Explanation:

Step1: Find the radius

The formula for the area of a circle is \(A = \pi r^{2}\). Given \(A = 28.26\) \(km^{2}\) and taking \(\pi=3.14\).
We solve for \(r\):

$$
LATEXBLOCK0
$$

Step2: Calculate the diameter

The diameter \(d\) of a circle is related to the radius \(r\) by the formula \(d = 2r\).
Since \(r = 3\), then \(d=2\times3=6\)

Answer:

\(6\) kilometers
