What is the volume of the sphere? (I'm giving medals)

Use the formula \[\Large V = \frac{4}{3} * \pi * r^3\]

OpenStudy (anonymous):

use the equation above and it looks like your radius is 10... so apply to the equation (substitute 10 for r) and solve! what do you get?

OpenStudy (anonymous):

i got 4188.79

jimthompson5910 (jim_thompson5910):

I'm getting (4/3)*pi*10^3 = 4,188.7902047864 so it looks like you got it

OpenStudy (anonymous):

yup, always listen to jim_thompson5910 haha he's never ever ever wrong

jimthompson5910 (jim_thompson5910):

I wish, but thanks lol

OpenStudy (anonymous):

Do I just enter in 4188.79

jimthompson5910 (jim_thompson5910):

it depends on how they want you to round

OpenStudy (anonymous):

hahaa he's also modest :P and yes, if the problem is asking you to round to two decimal places, then 4188.79 is right

jimthompson5910 (jim_thompson5910):

that's assuming they want the approximate answer

OpenStudy (anonymous):

To the nearest 2 decimal places.

OpenStudy (anonymous):

yeah, so 4188.79 is what you want to write down :)
