Question

Which has the greater volume a cylinder of height $22cm$ and diameter of base $20cm$ or a cube with length of edge $19cm$ and by how much? (Use $\pi =3.14$)

• A. The cylinder by $39c{m}^3$
• B. The cylinder by $47c{m}^3$
• C. The cylinder by $29c{m}^3$
• D. The cylinder by $49c{m}^3$

Answer 1

The correct option is D The cylinder by $49c{m}^3$

$h=22cm,r=10cm$of cylinder
Volume of cylinder$=\pi \left({10}^2\right)\left(22\right)=6908c{m}^3$
$edge=19cm$
Volume of cube$=6859c{m}^3$
Volume of cylinder- volume of cube =49 cubic cm
