Answer:
Change in height of the parasail after 5 minutes = 79.8 feet.
Explanation:
Change in height = Absolute value of the differences of the initial height and final height.
Initial height of parasail = 200.6 feet.
Final height parasail = 120.8 feet.
Change in height of the parasail = 200.6 - 120.8 = 79.8 feet.
Change in height of the parasail after 5 minutes = 79.8 feet.
Answer:

Step-by-step explanation:
the volume of a cylinder is given by:

and the volume of a cone is given by:

since both have the same height and radius, we can solve each equation for
(because this quantity is the same in both figures) and then match the expressions we find:
from the cylinder's volume formula:

and from the cone's volume formula:

matching the two previous expressions:

we solve for the volume of a cone
:

substituting the value of the cylinder's volume 

Im pretty sure he can travel 800 miles not counting the truck rental fee. Im not 100% sure though.
Hope this helps!
