- If my calculations are correct, half of 18 is 9! -Carla
- Okay! The formula for sphere is V = 4/3 𝝿r3. But first we need to find the radius! The Diameter goes all the through the shape instead halfway through like the radius. so the question is, what is half of 18! - Mary
- Yup! now we can use the formula. 4/3 x 3.14 x 9 to the 3 power! - John
- Of course! If I'm not mistaken we should have 3,053.08 liters of water. But to be safe we should round it up 3,053! -Carla
- Okay, Carla, do you think you can do another calculation for us? - Mary
- Nice one, Carla! - John
- You got it chief! Hmmm... If you multiply 3,053 x 3 we should get... 9,151 liters! - John
- John, you can do the last calculation for us if you want! - Mary
