What is an equation in point-slope form for the line perpendicular to y = 2x + 13 that contains (8. 4)? A. y + 4 =--(x-8)
Cy+4= 2(x + 8)
2
B. X+4 = 2(y-8)

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 !
