Step-by-step explanation:
Given that,
Radius of a cone, r = 13 cm
Slant height of the cone, l = 20 cm
We need to find the surface area of the cone. The formula for the surface area of the cone is given by :

Put all the values,

So, the surface area of the cone is
.

Step-by-step explanation:
Answer:
6 units long.
Step-by-step explanation:
Given:
A polygon drawn on a graph.
In order to determine the distance of the horizontal line at the top, we find the coordinates of the end points and then use distance formula to find the exact distance.
Let us label the polygon as ABCD as shown below. AB is the length of the horizontal line.
Coordinates of A are
as seen in the graph.
Coordinates of B are
as seen in the graph.
Now, distance formula for two points
is:

Therefore, the horizontal line at the top is 6 units long.
A + (-5) = -12
First isolate your variable so move the -5 over (by adding 5 to both sides)
Then you will have a = -12+5
Simplify and you get A= -7
