The equation for circumference is
$c = 2r\pi$
Since you have the diameter you can either divide the diameter (d) by two to get the radius (r), or you can divide two from the equation to give you
$c = d \pi$
So the circumference is 33*pi meters, approximately 103.62 meters

The circumstance is 33*pi meters. So it’s about 103.62 meters

Answer:

D. Segment YZ is located at Y(0,1) and Z(−2,1) and is one-third the size of segment Y'Z'

Step-by-step explanation:

When you dilate a point by a factor of x from the origin, you multiply its coordinates by the same factor.

Thus, if the coordinates of the original point are (1,2) and the scale factor is 3, those of its image are (3,6).

If Y'Z' has endpoints at Y'(0,3) and Z'(-6,3) and was dilated by a factor of 3, the coordinates of the endpoints of the pre-image were ⅓ those of the image.

The figure below shows the segments YZ and Y'Z'.
