Find the axis of symmetry and the vertex of
the equation below.
n^2+ 6n = 0

axis of symmerty = x coordinate of vertex = -b/2a

-6/2 = -3 = x

vertex = (-3,y)

-3^2 +6(-3)

9-18 = -9 = y

(-3,-9) = vertex

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 !
