Which confirms that rectangle abcd and rectangle efgh are similar after the similarity transformation of a rotation followed by a dilation? a) ad/gh = cd/eh = bc/ef = ab/fg = 4 b) ad/gh = cd/eh = bc/ef = ab/fg = 2 c) ad/eh = cd/gh = bc/fg = ab/ef = 2 d) ad/eh = cd/gh = bc/fg = ab/ef = 1/2

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
