A sphere, cylinder and cone of dimensions radius =r cm and height =2 r cm are made. Which one has the… · ABC26GN4985

Volume of sphere $=\left(\frac{4}{3} \pi r^{3}\right) \mathrm{cm}^{3}$. Volume of cylinder $=\left[\pi r^{2} .(2 r)\right] \mathrm{cm}^{3}=\left(2 \pi r^{3}\right) \mathrm{cm}^{3}$. Volume of cone $=\left[\frac{1}{3} \pi r^{2} \cdot(2 r)\right] \mathrm{cm}^{3}=\left(\frac{2}{3} \pi r^{3}\right) \mathrm{cm}^{3}$. Clearly, cylinder has the greatest volume.
