What is the hypotenuse of a triangle?

Answer is in the explanation.

It is the longest side the right triangle.

Step-by-step explanation:

It is a side in a right triangle.  

The biggest angle in a right triangle is it's right angle, the 90 degree angle.

The other two angles are acute.

The biggest side, the side that is opposite the 90 degree angle, is the hypotenuse.  

In the right triangle, the side that is not touching or helping to create the 90 degree angle is the hypotenuse.

answer is c

step-by-step explanation:

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 !
