Triangle AA'B'C' is the image of A ABC under a dilation. What is the scale factor of the dilation

The radius of a sphere is 3 inches. which represents the volume of the sphere?

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte

Sate why the measure of angle d is 120 degrees
