According to these three facts, which statements are true? circle w has center (−3, 0) and radius 8. circle v is a translation of circle w, 2 units down. circle v is a dilation of circle w with a scale factor of 2. select one or more answers the center of circle v is (−5, 0). circle v and circle w are similar. the radius of circle v is 16. circle v and circle w have the same center. 2.suppose x is any positive number. circle 1: center (0, 0) and radius 2x circle 2: center (0, 0) and radius 10x why is circle 1 similar to circle 2? circle 2 is a dilation of circle 1 with a scale factor of 0.2. both circles have congruent diameters. circle 2 is a dilation of circle 1 with a scale factor of 5. circle 1 and circle 2 have equal areas.
