Question

The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?
A.
V = r2
B.
V = r3
C.
V = r3
D.
V = r2
I dont need a whole explanation i just need the answer

Answer 1

Answer:

in my oppimion it would be D.

Answer 2

$\bf\large\underline\pink{Answer:-}$

If the height is 2 times the diameter of the base, then it is four times the radius. So, first , let r be the radius. With this example, the height of the base is 4r. The volume 'V' of the cone is calculated through the equation:

V = πr²h/3

Now we substitute the correct variables:

V = 4πr³/3
