Answer: first option
Step-by-step explanation:
The formula for calculate the surface area of a cone is the shown below:

Where: s is the slant height and r is the radius.
As you can see in the figure the slant height and the radius are:
s=18 cm and r=6 cm
Therefore when you substitute the values shown above into the formula, you obtain that the result is:
cm²

Answer:
The median is 9
The Range is 13-5=8
The mean is 5+5+9+11+13/5=43/5=8 3/5=8.6
Answer:
9
Step-by-step explanation:
The equation graphed from these points is y=3x+9, therefore the y-intercept is 9.
