What is the height of the can?

The height is 5 inches.

Step-by-step explanation:

The surface area of a cylinder uses the formula   A= 2rh + 2r^2  

so as you could see in the equation there is an h in in it which re

presents the height and we know the diameter is 2 so we need to find the radius and the radius is 1 because half of 2 is 1 or half the diameter is the radius.

Now put the radius into the equation and  and solve for the height and as you could see the surface area is left in terms of pi.  

12 = 2 * 1 * h + 2 * 1  

12= 2 * h + 2

-2                 2

10 = 2h

h =5

the answer is 99.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
