For 2/3 = 4/6 and 4/8 = 1/2
The correct answer is A, it has -1. While B's got 1.
Now the formula for the area of a circle is: πr². So we take 3 and just put it into the equation. π·3²=28.27. This is the area of the circle. Now the rate of change I think would just be the difference between the radius and the area of the circle so 28.27-3=25.27.
The answer is the 2nd one because on the left side you combine like terms and when you do your sum is bigger than 5 so b is your answer
