Find the volume and curved surface area of a right circular cylinder of height 21 cm and base radius 5 cm.

$\\\text{For a right circular cylinder, } \\ \text{Volume } = \pi r^{2}h = \pi \times 5^{2}\times 21 \ cm^{3} =1650 \ cm^{3} \\ \text{Curved surface area} = 2\pi rh = 2\pi \times 5\times 21 \ cm^{2} = 660 \ cm^{2}$
