Help on #9 I don't get it!

Fantom [35]

Your trying to rearrange the equation with v were the r was.

2( v - h ) / k = r

2( v - h ) k / k = rk

2( v - h ) = rk

2( v - h ) / 2 = rk / 2

v - h = rk / 2

v - h + h = rk / 2 + h

v = rk / 2 + h

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?

grigory [225]

Answer:

$\frac{4}{3} \pi r^3$ .

Step-by-step explanation:

Let's say that the radius is r. The base diameter is two times the radius, or 2r.

Since the height is two times the diameter, the height is 2 * 2r = 4r.

The volume of a cone is 1/3 * h * pi * r^2. So, the volume of the cone is 1/3 * 4r * pi * r^2 = 1/3 * pi * 4r^3 = 4/3 * pi * r^3.

So, the volume of the cone is $\frac{4}{3} \pi r^3$ .

Hope this helps!
