Question

If the circumference is 307.72 what is the diameter

Answer 1

By definition, $\pi$ is the ratio between the circumference and the diameter:

$\pi=\dfrac{C}{d}$

Which implies

$d=\dfrac{C}{\pi}$

So, your diameter is

$d=\dfrac{307.72}{\pi}$

Answer 2

Answer: 98 units

Step-by-step explanation: C=d x pi

Divide circumference by 3.14. You will get d=98
