Answers (1)

Radius of cylinder (r) = 14cm

Height (h) = 21cm

$ Curved surface area $ = 2 \pi rh\\ = 2 \times \frac{22}{7} \times 14 \times 21 \\ = 1848 \ cm^2 \\ $ Total surface area $ = 2 \pi r(h+r)\\ = 2 \times \frac{22}{7} \times 14 \times (21+14) \\ = 3080 \ cm^2 \\ $ Volume of the cylinder $ = \pi r^2h\\ = \frac{22}{7} \times 14^2 \times 21 \\ = 12936 \ cm^3
