r = 12.3 cm.....

Answer 3

so pi x 12.3?

Answer 4

(4/3)pi x (12.3)^3

Answer 5

how do we multiply with a fraction?

Answer 6

\[\frac{ 4 }{ 3 } \times \pi \times (12.3)^3\]
\[\frac{ 4 }{ 3 } \times 3.14 \times 1860.867\]
proceed

Answer 7

5843.12238

Answer 8

now \[\frac{ 5843.122 \times 4 }{ 3 }\]
