Pls helps 50 points

Here's the solution,

volume of cylinder :

=》

where,

r = radiush = height

now, let's solve

=》

=》

So, volume = 2000.2 cm³

The answer simplified would be. -6300x

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
