The axis of symmetry for the function f(x) = -2x2 + 4x + 1 is the line x = 1. Where is the vertex of the function located? (0,1)
(1,3)
(1,7)
(2,1)

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 !

add a picture or measurements so i cab
