The formula for finding the surface area of a cone using the slant height is:
SA = pi * r * l + pi * r^2
where SA stands for surface area, r stands for radius, and l stands for slant height
Therefore, we can simply plug in all of the given values into the formula to get our answer.
The equation we would solve would be:
SA = 3.14*4*5+3.14*4^2
This gives us 113.04
The answer that is closest to this would be 113
Therefore, the answer is 113

Answer:
1.1818...
Step-by-step explanation:
Divide 13 by 11
13 ÷ 11 = 1.1818...
Answer: 1.1818...
Let x be width.
Length: 2x
98=2x(x)
2x^2=98
x^2=98/2
x^2=49
x= sqrt(49)
x= 7 (not -7 because distance cannot be in negatives)
Therefore, the dimensions are 7"x14"
Hope I helped :)
Answer:
x = 25
Step-by-step explanation:
The triangle is isosceles, therefore, the base angles are the same
62 + 2x + 9 + 2x + 9 = 180
62 + 4x + 18 = 180
4x = 180 - 62 - 18
4x = 100
x = 100/4
x = 25
