the volume of a sphere can be give by v-4.18879r^3. you have to design a spherical cotainer that will hold a volume of 55 cubic inches. what should the radius be ?

Question

anonymous · Answer

If we solve the given equation for r in terms of v, we get
$$r = \sqrt[3]{v/4.18879}.$$

anonymous · Answer

Plug 55 into that formula , get a numerical answer and you're done.

it didnt come out too one of my answer choices .

anonymous · Answer

I got 13.13 inches.

anonymous · Answer

If that is incorrect (I suspect it is), then you have bad data.  The correct formula for the volume of a sphere is 
$$V = (4/3)pir^3.$$

anonymous · Answer

Lets see what happens if we work with this, going through the same process again.

anonymous · Answer

$$r = \sqrt[3]{3V/(4*\pi)}$$.

anonymous · Answer

I still get 13.13 inches.

anonymous · Answer

Forgot the cube root of that, which is 2.36 in.
