(A) 21cm
As we probably are aware,
Volume of cuboid = lbh
Where, l = length, b = broadness and h = tallness
For given cuboid,
Length, l = 49 cm
Broadness, b = 33 cm
Tallness, h = 24 cm
Volume of solid shape
![\[=\text{ }49\times \text{ }\left( 33 \right)\text{ }\times \text{ }\left( 24 \right)\text{ }cm3\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-5bf25e0fcf788fbaab5887ceb8695920_l3.png "Rendered by QuickLaTeX.com")
Presently,
Leave the range of 3D square alone r.
As volume of circle
![\[=\text{ }4/3\text{ }\pi r3\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-b1ce73ebb77db4e1c3f2a971d3230e68_l3.png "Rendered by QuickLaTeX.com")
Where r = range of circle
Too,
Volume of cuboid = volume of circle formed
Along these lines,
![\[49\left( 33 \right)\left( 24 \right)\text{ }=\text{ }4/3\text{ }\pi r3\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-c85aacaf2d4b5c7e1aea61b09e8d11b4_l3.png "Rendered by QuickLaTeX.com")
![\[\Rightarrow \pi r3\text{ }=\text{ }29106\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-ddc8235ed4ea8c5670b0d48adf42f174_l3.png "Rendered by QuickLaTeX.com")
![\[\Rightarrow r3\text{ }=\text{ }29106\times 22/7\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-e4d28829f499a1bc847f7098c507249c_l3.png "Rendered by QuickLaTeX.com")
![\[\Rightarrow r3\text{ }=\text{ }9261\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-271b9d89154d49e0e14cc0f84073dcd8_l3.png "Rendered by QuickLaTeX.com")
![\[\Rightarrow r\text{ }=9261\text{ }cm\text{ }=\text{ }21\text{ }cm\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-a98df4df4dde849b4079f68accb9bccf_l3.png "Rendered by QuickLaTeX.com")
Consequently, sweep of circle is 21 cm
