The volume of a cylinder is given by the formula v= pi^2h, where r is the radius of the cylinder and h is the height: which expression represents the volume of this cylinder?

Option B:

Step-by-step explanation:

We know that height of the cylinder is given by h = 2x + 7 and radius r = x - 3.

We know that the formula of volume of a cylinder is:

Volume of a cylinder =

Substituting the given values in the above formula to get:

Volume =

=

=

=

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
