The diameter of the circle is 10.86
Median is the middle of the number set so
5 8 10 20 25 30 35 40 45
its 25
T(x, y) = (x - 5, y - 6) since you are trying to translate back to the original point and therefor should do the reverse set of translations
Step-by-step explanation:

1 ton = 2000 ponds
Multiply: 2000x30=?
2000x30=60000
Hope that helped:)
