Answer:
The combination 9 mm, 6mm, 5mm will not form a triangle.
9 +6 = 15 > 5
6+5= 11 < 9
9+5 =14 > 6
Explanation :
because the side length of triangle does not obey triangle inequality theorem.
The triangle inequality theorem:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

How far does a wheel move when it rotates once? The length of the outside of the tyre? Isn't that the same as the circumference?
Answer:
B because 20 cm multiplayer by 9cm equals 180cm
The formula for the surface area of a cone is SA=(pi)(r^2)+(pi)(r)(l)
L is the slant height of the cone.
Because pi is in the answer choices, there is no need to multiply either by pi so the new formula becomes
SA=r^2+(r)(l)
Now you just plug in what you know
Sa=(8^2) + (8)(15)
Sa=64+120
Sa=184(pi)
*dont forget to put the pi back in since you took it out in the beginning of the equation*
Your answer is A.
Hope this helps :)
