Questions at easy, medium and hard levels. Pick a level and get a fresh set every time, with instant feedback.

Learn it Cylinder: $V = \pi r^2 h$. Surface area $= 2\pi r^2$ (two circles) $+ 2\pi r h$ (the curved side, which unrolls into a rectangle).

Example: A can has radius 4 cm and height 10 cm. Find V and SA (π ≈ 3.14).

  1. $V = 3.14 \times 16 \times 10 = 502.4$ cm³.
  2. Circles: $2 \times 3.14 \times 16 = 100.48$. Side: $2 \times 3.14 \times 4 \times 10 = 251.2$.
  3. SA = 351.68 cm².
