4/3 pi r^3
OpenStudy (zale101):
That's the volume formula for a sphere. Correct. Can you show me the step by step you used to get the answer c?
OpenStudy (narissa):
im just confused thats y im here
OpenStudy (zale101):
Volume of a sphere= 4/3 pi r^3
where r is the radius
and pi is the pi number rounded to 3.14
OpenStudy (zale101):
What is the radius in your question? Any ideas?

12.3
OpenStudy (zale101):
Correct.
OpenStudy (narissa):

OpenStudy (zale101):
So C is right :)
OpenStudy (zale101):
Next time, it is better to write down how you got the answer and write the steps you took to solve it. Ok?

In that way, it would be easier for tutors to tutor the part you don't understand.
imqwerty (imqwerty):
option C is this-> \(7790.82 \color{red}{\pi}\)
OpenStudy (narissa):
so it would be b?
OpenStudy (zale101):
Oh yes. THanks qwerty!
OpenStudy (zale101):
Pi is not multiplied in.

@narissa
OpenStudy (zale101):
Solve the volume without calculating pi. Can you do that?
OpenStudy (narissa):
its b
OpenStudy (zale101):
What will you get?

V=(4/3)(12.3)^2 pi
OpenStudy (zale101):
How did you get B? Show me the steps you took.
OpenStudy (narissa):
ok yes i got it its a
