I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.
The first thing you should do for this case is find the amount that Michael has traveled.
For this we have to multiply the distance to the store and the percentage traveled.
We have then:
(3/8) * (4/5) = 12/40
Simplifying we have:
(12/40) * ((1/2) / (1/2)) = (6/20) * ((1/2) / (1/2)) = 3/10
answer
Michael has walked 3 / 10Km (80% of the way to the store)
420-x=76 try that equation if not you might want a math tutor.
The graph would be shifted up (8--6), or 14 units.
