Find the diameter of a cone that had a volume of 56.52 cubic inches and a height of 6 inches

bulgar [2K]

Answer: 5.98 inches

Step-by-step explanation:

1. You have that the formula for calculate the volume of a cone is:

$V=\frac{r^{2}h\pi}{3}$

Where V is the volume, r is the radius and h is the height.

2. By definition, the diameter is twice the radius. Therefore, you need to solve for the radius:

$V=\frac{r^{2}h\pi}{3} \\3V=r^{2}h\pi\\r=\sqrt{\frac{3V}{h\pi}}$

3. Substitute values:

$r=\sqrt{\frac{3(56.52in^{3})}{(6in)\pi}}=2.99in$

4. The diameter is:

$D=2r\\D=2(2.99in)\\D=5.98in$
