You could factor a 7 out of 7 + 14 to get 7(1 + 2).
This would equal the same thing as 7 + 14, which is 21.
7 * 3 = 21.
21 can be factored like so:
1 * 21 = 21
3 * 7 = 21
Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180 degress
Replace each of the x values given to see if they give 0.
0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259
0=(1)³+(1)²-1
0≠1
Therefore, you can see that the solution would have to be between 2/3 and 1.
Hope I helped :)
To find this, we need to find the Surface area of the lateral surface of the cone (without the circle base).

Now we just need to plug what we know into the equation


Wither you can keep your answer in pi or take it out of pi, depending on what the requirements are.
To take it out of pi you need to multiply 6 by pi (remembering to use 3.14 as pi in most cases since that is what is generally accepted on tests and exams).

Then rounding to the nearest square inch which would mean that the amount of paper needed is =19in²
