A=pie×radius squared is the area formula of a circle. The circumference formula or a circle is C=pie×diameter. 615.75=(3.14)(radius) squared. Divide both sides by the 3.14. What ever 615.75 divided by 3.14 is-is radius squared. The square root is your radius. The radius is half the diameter, so double what you have right now as the radius to get the diameter. Now since C=pie×diameter, your circumference is your pie×your diameter. Whatever your answer is-is your circumference.
I believe the answer is 6
Only because I see that I can divide 3 and 2 and I know that the answer is 6
Quotient means division....less then means subtract
(y/2) - 5
Where's the graph? If you can give me the graph then I'd be able to answer for you.
