Answer:
The answer would be 50% or 1/2
Step-by-step explanation:
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.
It would be associative property because the order of the numbers stayed the same
The answer is A, yes his answer is reasonable because 6 times 0.74 is 44.4
