Answer:
C/d = 31.4/10
Step-by-step explanation:
We know the formula of the circumference, which ir:
C = pi*d
Where C is the circumference and d is the diameter of the circle. If we want to know the value of the pi number we just need to divide both sides of the equation above by d:
C/d = pi*d/d
C/d = pi
Thus, we can write pi as the ratio C:d or C/d, which means, how many times the diameter enters on the circumference. In our case is:
pi = 31.4/10 = 3.14
And 3.14 is how we usually use the pi number.
