Which of the following 3 side lengths will yield a triangle? 2cm, Зcm, 5cm
15ft 7ft, 2ft
13mi, Smi, 9mi
1km, 2 km, 3km

Let us assume that a, b and c are 3 “lengths". Also let us assume that “c’ is the longest length. Now we can say that the combined lengths of sides “a” and “b” must be greater or at least equal* to the length “c” for these lengths to be the sides of a triangle. Otherwise the opposite ends of “a” and “b” would not meet therefore being an incomplete triangle “ a gestalt in the German language”.

*If a+b=c then we would have a degenerate triangle-it would technically be a triangle but would occupy no area in a 2-D universe.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
