Surface Area of a cone is
<span>pi * r * s + pi * r^2 </span>
<span>s is the side length, since you have 10 ft diameter, you know radius is 5. And since height is 12. With this, you have a 5-12-13 triangle, and s=13. </span>
<span>so </span>
<span>pi * 5 * 14 + pi * 5^2 = 95 pi or 298.3 </span>
<span>divide 298.3 by 15 and you get 19.88, you round up, so 20 is the answer </span>
Answer:
so the 2 questions i see are surveys so... you have to answer them with truth on your own self
Step-by-step explanation:
Answer: E. 4/5
Step-by-step explanation: You have to put the decimal (0.8) over its place value. So in this case 0.8 turns into 8/10. Then you must simplify 8/10, by dividing the numerator (8) and the denominator (10) by the greatest common factor (2). Which gives you the answer 4/5.
When you compare two functions f(x) and g(x), you're looking for a special input 
such that
Since you have the table with some possible candidates for , you simply have to choose the row that gives values for f(x) and g(x) that are as close as possible (the exact solution would give the same value for f(x) and g(x), so the approximate solution will give values for f(x) and g(x) that are close to each other).
In your table, the values for f(x) and g(x) are closer when x=-0.75
