Find the radius of the sphere with a volume of 32/81π cubic yards. Write your answer as a fraction in simplest form.
Vilka [71]

Answer:

2/3 yards or 2 feet

Step-by-step explanation:

The formula for the volume of a sphere is \frac{4}{3}\pi r^3, meaning that you can set up the following equation:

\dfrac{32\pi}{81}=\dfrac{4}{3}\pi r^3

Divide both sides by \frac{4}{3}\pi:

\dfrac{8}{27}=r^3

Take the cube root of both sides:

r=\dfrac{2}{3} yards. Hope this helps!

PLS HELP What is the equation of the parabola? coordinate plane with a parabola facing up with vertex at 0 comma 5, the point 0
lord [1]

Answer:

y=\frac{1}{8}x^2+5

Step-by-step explanation:

We want to find the equation of a parabola with vertex (0,5), focus at (0,7) and directrix y=3.

This is given by (x-h)^2=4p(x-k)

where p=2, h=0, and k=5

We substitute these values to get:

(x-0)^2=4*2(y-5)

This simplifies to:

x^2=8(y-5)

We solve for y to get:

y=\frac{1}{8}x^2+5
