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

What is the y-intercept of y=2/3 x +2
BaLLatris [955]

Answer:

2

Step-by-step explanation:

Since the equation is in y=mx+b form, the y-intercept can easily be identified by just looking at it.

Knowing that b is the y-intercept and m is the slope. Any number in place of these variables are y-intercept and slope respectively.

That being said, the y-intercept is 2.
