Question

In a circle, what is the diameter in relation to the radius?

A 1/2r
B
2r
C
4r
they are equal
Click the button or type the letter t

Answer 1

And by definition the radius would be lower than the diameter and we have the following relationship:

`D= 2r`

And then the best answer would be:

B 2r

Explanation:

When we have a circle we know that the area is given by:

`A= \pi r^2`

And we also know that the diameter is the distance between two any points in the circle passing through the center.

And by definition the radius would be lower than the diameter and we have the following relationship:

`D= 2r`

And then the best answer would be:

B 2r
