What is the height of a cone with a radius of 3 inches and a volume 4 cubic inches

Cone volume = (pi*r*r*h) / 3

where r is radius and h is height

Put in what we know

pi is about 3.1415

4 = (3.1415*3*3*h) / 3

4 = 28.274*h/3

4 = 28.274/3*h

4 = 9.425*h

h = 4/9.425=0.424

and that would be in inches so

Height is about 0.424 inches.

It can be rounded to 0.42
