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.
Idk if you are talking about independent and dependent variables but if you are then the independent variable is the variable that is changed or controlled and the dependent variable is the variable being tested and measured in a scientific experiment. Hope this helps!!!❤️
