Question

The circle will be dilated by a scale factor of 6. What is the value for n if the expression nPI represents the circumference of the circles in inches?

Answer 1

A dilation by a scale factor of 6 will cause the radius to increase by a factor of 6. So $r_{new} = 6r$. If we plug this value of r into the formula for the circumference of a circle we get $C = 2\pi r_{new} = 2\pi *6r = 12\pi r$

So basically N = 12r. You haven't given me any original radius, so I can't give you a constant for N, but if you do have that original radius you can just plug that into 12r.

Based on your comment, N = 12 * 9 = 108 inches

108
