Parallelogram A'B'C'D' (not shown) is the image of
parallelogram ABCD after a rotation of 180° about
origin. Which statements about A'B'C'D” are true?
Select each correct statement.

A. A'B' is parallel to B'C'
B. A'B' is parallel to A'D'
C. A'B' is parallel to C'D'
D. A'D' is parallel to B'C'
E. A'D' is parallel to D'C”

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

i think its a.

hope this

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
