The distance the tip travels is
2π·(40 m) = 80π m
Then its speed is
(80π m)/(10 s) = 8π m/2 ≈ 25.1 m/s
Answer: .625 (yes he did leave enough

Answer:
Option B is right answer.
Step-by-step explanation:
Yes, it is true hat the rectangle EFGH is a result of dilation of rectangle ABCD with a center of dilation at the origin.
Also according to the given image, we can see that the scale factor of the dilation is greater than one as the new image is bigger than the pre-image.
Also, we can see is that ∠A=∠B=∠C=∠D=∠E=∠F=∠G=∠H=90°
So, we can say that option B is true - Yes, because both figures are rectangles and all rectangles are similar.
