A circle is painted in the center of a basketball court. If the diameter of the circle is 12 feet, what is the approximate amount of space inside of the circle? (Use 3.14 as an approximation of pi.)

Answer:
37.68
Step-by-step explanation:
You have to multiply the diameter by pi (3.14). If it was radius, then you have to multiply the radius twice with pi. (R x R x 3.14)
ANSWER: 37.68
Why? Well this question is asking for the circumference...and you get the circumference by multiplying 3.14 (pi) by the diameter.
Final Notes: The formula for finding the circumference with the diameter is
(C = [tex]\pi[/tex]d) (diameter times 3.14)
if you want the formula for finding the circumference with only the radius here you go, (Radius times 3.14 then times it by 2)
(C = 2[tex]\pi[/tex]r)
Hope this helps!!
