Answer:

The area of the circle is 19.625.

Step-by-step explanation:

  1. To find the area of a circle, you use the formula A=πr², so you need the radius. The radius is half of the diameter, so half of 5 is 2.5.
  2. Next, you just plug the numbers into the formula (I used 3.14 for pi). A=(3.14)(2.5²).
  3. A=(3.14)(6.25)
  4. A=19.625
  5. Round to your liking/whatever the question asks for and add the units the question asks for as well. If there aren't any offered in the question, just use units squared if you have to give any.
