Question

The diameter of a circle is 6 kilometers. What is the circle's area?
Use 3.14 for ​.

Answer 1

28.26

Explanation:

First find the radius by dividing the diameter by 2 (6/2 = 3) Now that we know that the radius is 3 you multiply it by 3 because you need the radius squared. (3*3 = 9) and then you multiply 9 by 3.14 and get your answer of 28.26.
