The circles are identical. What is the circumference of each circle? Circle 1: radius of 2x; Circle 2: diameter of 2x+3. Choices are: A. 3/2 B. 3 C. 1.5π D. 9π/4 E. 3π F. 6π

F. 6π is the correct answer

As the diameter of the 2nd circle is 2x+3, its radius will be (2x+3)/2 which is equal to x + 1.5  

But as it is identical to the 1st circle their radii will be equal.

Therefore, 2x = x + 1.5

Therefore, 2x - x = 1.5

Thus we get that x = 1.5

Therefore, r (radius) = 2x = 2*1.5 = 3

Now we can find the circumfrence by the equation circumference = 2πr

Therefore, circumference = 2*π*3 = 6π

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
