Question

what is the approximate volume of the sphere?

Answer 1

Do you know the formula for volume of a sphere?
\( V = \dfrac{4}{3} \pi r^3 \)

If you wanted to approximate, you could use the approximation of pi, \(\pi \approx 3.14 \), or any other common approximation of pi that you normally use in class (22/7, 3.1415.. etc)

Answer 2

i got 294.911?

Answer 3

I got something different. What did you plug in for your information?
r = ?
pi = ?

Answer 4

r i put 1.59? or is it 5?
pi i put 3.14

Answer 5

The radius is half the diameter, which is 10 meters. So radius = 10/2 = 5 m. :)

Answer 6

oh alright. i keep trying different ways, but cannot end up with the answer?

Answer 7

If we put in r=5, and pi = 3.14.
4/3 * 3.14 * 5^3 We could simplify that 5^3 = 5*5*5 = 125
4/3 * 3.14 * 125
We could use a calculator here. That is clear?

Answer 8

yes.

Answer 9

OH, would it be 523.33?

Answer 10

Yep, that is what I got as well. :)

Answer 11

Sure, that's fine.

Answer 12

It looks like the website hit another snag.
I saw your question as "Find the surface area of the [same] sphere"
Which means, we want to use the surface area formula:
S = 4 pi r^2
Same numbers in as before: r=5, pi = 3.14
