pls help i will fan and medal

Answer 1

4500 pi in^3?

Answer 2

hint:
the requested volume is given by the subsequent formula:
\[\Large V = \frac{{4\pi }}{3}{\left( {\frac{D}{2}} \right)^3}\]
where \(D\) is the diameter

Answer 3

I think that your answer is correct!

Answer 4

ok thank you! do you have time for a few more? @Michele_Laino

Answer 5

ok!

Answer 6

C?

Answer 7

we can apply the same formula above:
\[\Large V = \frac{{4\pi }}{3}{R^3} \simeq \frac{{4 \times 3.14}}{3} \times {3^3} = ...?\]

Answer 8

yes! I confirm option C

Answer 9

okay. I have 2 more left

Answer 10

that's right!

\[\Large V = \frac{{4\pi }}{3}{R^3} \simeq \frac{{4 \times 3.14}}{3} \times {12^3} = ...?\]

Answer 11

last one!

Answer 12

that's right!

\[\Large V = \frac{{4\pi }}{3}{R^3} \simeq \frac{{4 \times 3.14}}{3} \times {21^3} = ...?\]

Answer 13
