Question

As the diameter of the circle increases what happens to the circumference?

Answer 1

It increases.

Explanation:

The circumference of a circle is given by
`c=2pir`
Where `c` is the circumference, `r` is the radius of the circle.
But since double of the radius is called diameter i.e. `2r=d`
Where `d` is the diameter of the circle.
`implies c=pid`
Since `pi` is a constant
`implies c propd`
From above relation we can conclude that if the diameter of the circle increases than the circumference of the circle also .
