The answer to the question is D. It took me so long cuz' my phone died. *sry*
Using it's concept, the approximate perimeter of pentagon ABCDE is given as follows:
34.4 units.
<h3>What is the perimeter of a figure?</h3>
The perimeter of a figure is given by the sum of the lengths of it's outside dimensions.
In this problem, the vertices are in a coordinate-plane, hence the distances are found using the formula for the distance between two points.
<h3>What is the distance between two points?</h3>
Suppose that we have two points,
and
. The distance between them is given by:

The length of segment AB is:

The length of segment BC is:

The length of segment CD is:

The length of segment DE is:

The length of segment EA is:

Hence the perimeter is:
P = AB + BC + CD + DE + EA = 9.2 + 5 + 6 + 5 + 9.2 = 34.4 units.

#SPJ1
Answer:
Step-by-step explanation:
The volume of a cylinder is expressed as
V = πr^2h
Where
π is a constant
h is the height of the cylinder
The volume of a cone is expressed as
V = 1/3πr^2h
Where
π is a constant
h is the height of the cone
If the cylinder and a cone have congruent bases and the same volume, it means that
πr^2h = 1/3πr^2h
πr^2 cancels out on both the left hand side and right hand side of the equation. It becomes
h = h/3
It means that the height of the cone is 3 times the height of the cylinder. Therefore,
If height of cylinder = 4 cm, height of cone = 12 cm
