x = -1 and y = 5

Step-by-step explanation:

Let the equation of the line be y = mx + c

sub m = 2/3 and (-2, 5):

5 = 2/3(-2) + c

c = 5 - 4/3

c = 11/3

sub (x, 3):

3 = 2/3x + 11/3

2/3x = -2/3

x = -1

sub (-2, y):

y = 2/3(-2) + 11/3

y = 5 (tech it's given in question for this y value)

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 !
