Answer: C
Step-by-step explanation:
To find the surface area of a cone, you use the formula 
. Since we are already given the height and radius, all we have to do is plug in the values and solve.
[solve inside of square root]
[parenthesis]
[multiply]
Therefore, the closest answer is C.
Subtract 1 to 13. so you got 12. divide 4 so you can get the S by it self.S=3.
Y=mx+b
m=slope
solve for y
5y=x-3
divide both sides by 5
y=(1/5)x-(3/5)
slope=1/5
C is answer
Answer:
x = 20
Step-by-step explanation:
**CORRECTION** 21/2 because when you simplify it (dividing the top and the bottom by 2) you get 21/2. My first asnwer was a mixed number
