I am not sure either
Step-by-step explanation:
Let

denote the particle's position. Then its velocity is given by


The speed is then given by the absolute value/magnitude/norm of the velocity function,
$ 40 ..... 100 %
$ 28 ..... x %

The % of change is 70 %.
This is equivalent with:
- the final price ($ 28) is 70 % from the initial price ($ 40)
- the initial price ($ 40) was reduced with 30% giving the new price as:

Answer:
494.8
Step-by-step explanation:
Volume of cylinder = 2pierh + 2pier^2
= 2*3.14*4.5*13 + 2*3.24*4.5^2
= 494.8
