Is triangle A'B'C' a dilation of triangle ABC? Explain.

A. Yes, it is an enlargement with a scale factor of 3.
B. Yes, it is an enlargement with a scale factor of Eight-thirds.
C. No, it is not a dilation because the points of the image are not moved away from the
center of dilation proportionally.
D. No, it is not a dilation because the sides of the image are proportionally reduced from the pre-image.

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

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

40 x 50 = 2000
