It is a solid shape that contains lateral surface and two circular bases which are parallel and congruent.
ad-work [718]

Answer:

B (cylinder)

Step-by-step explanation:

Two <u>circular</u> bases which are parallel and congruent :

This basically means that the shape contains a circular base (supposedly the bottom), but since it has two bases, its on the top and the bottom. Because it's congruent, the bases are both equal in shape and size. It is also parallel as well, in which the bases have the same distance between them.

The cube doesn't have any circular bases.

The sphere doesn't have any faces, nor edges.

A cone has a circular base, but it doesn't have two.

A cylinder has two circular bases, as well as they are parallel and congruent.

So, your answer is B (cylinder).

Hope this helped !

attashe74 [19]

Answer:

Step-by-step explanation:

Absolute Change = final change in 2017 sales  - initial change in 2016 sales  =  $847,000,000 - $885,100,000 = 38,100,000

Relative Change = (Final - Initial change)/initial change x  100% = 38,100,000/885,100,00 x 100% = 381/8851 x 100% = 0.0430459835 x 100% = 4.30%
