hey may I jump in to give my help? :)

3. IrishBoy123

go for it mate!

4. anonymous

Sure.

I got V≈2334.67m³ is it right ?

6. anonymous

ok I really hate math but I love to solve these I like the challenge.... anyways :) you would have you radius = 9 *3.14 which is pi then divide. one you do that I will say what to divide by. :) btw that is how I was taught the easiest way by far

7. anonymous

Well for some reason that's not one of the answer choices.

8. IrishBoy123

$V = \frac{4}{3} \pi r^3$

Here are the options: A) 3,829.7 yd^3 B) 3,052.1 yd^3 C) 381.5 yd3^3 D) 339.1 yd^3

$V = \frac{ 4 }{ 3 }\pi r^3 = \frac{ 4 }{ 3 }(3.14)(9)^3 \approx 3044.4498yd^3$
