When you look at the two cylinders with these values of r and h, what do you notice about the proportions of the cylinders?

Elden [556K]

Answer and Explanation:

Volume of a cylinder is given by

V= Pi*r²*h

where v= volume of the cylinder

Pi is constant = 22/7 or 3.14159

r= radius of the circle of the cylinder

h= height of the cylinder

If two cylinders are measured proportionally to the other based on radius and height of each cylinder, we look at the proportional equality of the ratio of the radius and height of one cylinder to the other. If one cylinder for example has ratio of radius and height =2/4 then it is proportional to the other cylinder with ratio 1/2

HELP PLEASE ASAP!!!!!!!!!!!!!!!!!!!!

balandron [24]

They added 5+16 but instead they should've divided 42/5.

Hope this was fast enough!
