Question

complete the informal argument for the formula for the circumference of a circle by using the drop - down arrow to choose the correct words. when we measure the circumference and diameter of several circles, we can notice a pattern in their ratio. if we drop - down 1 the drop - down 2 by the drop - down 3, the result will be approximately equal to drop - down 4 for all circles. this value can be represented by the symbol π. this gives us a way to express the circumference as c = π×d

Explanation:

Step1: Recall the definition of pi

Pi ($\pi$) is defined as the ratio of the circumference of a circle to its diameter. Mathematically, $\pi=\frac{C}{d}$.

Step2: Fill in the blanks

If we divide the circumference by the diameter, the result will be approximately equal to $\pi$ for all circles.

Answer:

If we divide the circumference by the diameter, the result will be approximately equal to $\pi$ for all circles. So the blanks should be filled as: divide, circumference, diameter, $\pi$
