Question

Marge pulled out the four measuring cups in the kitchen drawer and for each one recorded the diameter and found the circumference. She then divided the circumference by the diameter. What should she have gotten? A) Each time you get 0.32. B) Each time you get 0.64. C) Each time you get 3.14. D) Each time you get 6.28.

Answer 1

When you divide circumference you will get C) 3.14

Answer 2

It says that ,

She divides circumference by diameter

And we know the formulas for circumference and diameter

Circumference = $2\pi r$

And Diameter = $2 r$

And now lets divide circumference by diameter

Circumference/ diameter = $\frac{2\pi r}{2r}$ = $\pi$

It simplifies to $\pi$

So every time on dividing circumference by diameter , she will get $\pi$

And value of $\pi$ is 3.14 .

So everytime she will get 3.14

So option C is the correct answer.
