Which of the following values for x and y make the equation 4x + 2y + 3 = 19 true? a. x = 5, y = 3 b. x = 4, y = 5 c. x = 3, y = 2 d. x = 2, y = 5

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 !
