How will the circumference of the circle change if it is dilated by a scale factor of 4?
Stolb23 [73]

The circumference of a circle has the formula:

C = 2 π r

 

Now when it is dilated by a factor of 4, this only means that the radius is also multiplied by a factor of 4, therefore the new circumference is:

C’ = 2 π (4 r)

C’ = 8 π r

So it also grows 4 times.

 

Answer:

<span>The circumference will be 4 times greater than the original.</span>
