Question

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 1

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 =
`\pi`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
`\pi`r)

Hope this helps!!

Answer 2

37.68

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)
