Factor to find a Dimension Alvin has a tech store and needs cylindrical
containers to package his voice-activated speakers.
There are two different cylindrical containers. Both
are 3 in high. The volume information is given for
each type of container. Determine the radius of each
cylinder. How much greater is the radius of one
container than the other?
Volume 31x?in
Volume 1(3x2 + 30x + 75) in3

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

hello! just here for points! though i wish i knew!

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
