The total surface area of a cone with a radius of 7 and a slant height of 9 would be around 351.858.
The lateral surface area of a cone with a radius of 7 and a slant height of 9 would be around 197.92.
You can use cone formulas to fine the surface areas, like the formula to find the slant height of the cone, to find the height of the cone and then solve for the area.
Hope this helps!
Answer:
11/6
Step-by-step explanation:
To isolate the y on one side of the equation, you must first subtract 11x from both sides. Then the equation becomes -6y = -11x - 36.
Then you must divide both sides by -6 to isolate the y. The coefficient of the variable x becomes -11/-6, which is just 11/6.

Step-by-step explanation:
178.54-35.65=142.89

She bought 11 CDs
Answer:
$8/hour
Step-by-step explanation:
We will start by finding how much money she made before spending it. The amount of money she took home added to how much money she spent will give us this. (
). This means she made $48 before spending it.
Now we can solve for her wage. Let 
be her hourly wage
(the 6 is the number of hours she worked, this multiplied by her wage should give us 48)
This means that she made $8/hour.
That is the answer

Answer:
If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times. Similarly Rudy and Bloopin will be together 4!=24 times. So the number of ways they are not together is 120-24-24=72 ways.
Hope this helps. :)
Step-by-step explanation:
Spanish:
Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.
De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.
Espero que esto ayude :)
