Triangle ABC is similar to triangle EFD . What scale factor is required to dilate triangle ABC so that its image, A'B'C' , is congruent to
triangle EFD ?

the scale factor of triangle ABC to triangle DEF is 2. This means that the second triangle is 2 times as big. If you multiply a side from triangle ABC by 2, you get the length of the corresponding side of triangle DEF.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
