Answer:
5,575 cm³
Step-by-step explanation:
The formula for the volume of a sphere is 4π(r³/3).
4π(11³/3) {11 cubed is 1331.}
4π(1331/3) {I'll rearrange the problem a little bit.}
(4 * 1331)π/3 {Multiply 4 by 1331 to get 5324.}
5324π/3 {Multiply 5324 by π to get 16725.8393.}
16725.8393/3 {Divide 16725.8393/3 to get 5575.2797}
5575.2797. {Round this answer to the nearest whole number. 2 is less than 5, so round down to 5575.}
5,575 cm³
The approximate volume of a spherical balloon with a radius of 11 cm is 5,575 cm³.
