Volume of a cone = pi * r² * (h/3)

If your diameter is 2, then take half of that for the radius; your radius is 1

Now plug in your given info:

V = pi * (1)² * (7/3)
= pi * 1 * (7/3)
= 7pi / 3

V ≈ 7.3304

Your answer is option D.

How do you find the equation of a parabola given two x intercepts

Ivahew [28]

Let's assume that the parabola has the following intersections with the x axis:
x1 = p
x2 = q
To find the equation of the parabola, we write the following product of binomials:
(x-p) (x-q) = 0
Where,
p, q: intersections with the x axis.
When developing the product of binomials, we obtain the equation of the parabola.
Answer:
(x-p) (x-q) = 0
