Question
Which of the following is not the ratio between the circumference and diameter of the circle Select answersA 2π : 1 B π : 2 C22 : 7D π : 1
Solution
The ratio of the circumference to the diameter of a circle is always π (Pi), which is approximately 3.14159. This is also known as the definition of π.
Let's go through the options:
A. 2π : 1 - This is not the correct ratio. The ratio should be π : 1, not 2π : 1.
B. π : 2 - This is also not the correct ratio. The ratio should be π : 1, not π : 2.
C. 22 : 7 - This is an approximation of π, but it's not the exact value. However, it's often used as a simple fractional approximation of π in many calculations.
D. π : 1 - This is the correct ratio of the circumference to the diameter of a circle.
So, the options that are not the ratio between the circumference and diameter of the circle are A and B.
