Question

Which statement is true about the circumference of a circle?

The circumference is equal to the radius of the circle.
The circumference is equal to the diameter of the circle.
The circumference is found by multiplying mc005-1.jpg by the radius.
The circumference is found by multiplying mc005-2.jpg by the diameter.

Answer 1

The circumference is found by multiplying mc005-1.jpg by the diameter.

Remember - Circumference = pi r^2

Answer 2

Answer: The answer is (d) the circumference is found by multiplying pi by the diameter.

Step-by-step explanation: We are to select the correct statement from the given options that are true about the circumference of a circle.

We know that the circumference 'C' of a circle is given by

`C=2\pi r,`

Where 'r' is the radius of the circle.

So, 2r = diameter of the circle.

Therefore, the circumference is found by multiplying pi by the diameter of the circle.

Thus, (d) is the correct option.
