Answer:

The area is: 611.34

Step-by-step explanation:

The formula for the area of a circle is [tex]\pi *r^2[/tex] or 3.14 * radius squared. So how you would go about solving this is you would start off by dividing 27.9 by 2 to get 13.95, because the radius is half of the diameter. Then you would enter 13.95 in your equation: 3.14 * 13.95^2 to get 611.34
