Aline passes through (2, −1) and (4, 5). which answer is the equation of the line? −3x y=−7−3x y=−7 −3x y=17−3x y=17 −3x 5y=13−3x 5y=13 −3x 5y=−13

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 !
