(Q6) A right circular cylinder has radius 14 cm and height 21 cm. Find its

(i) area of base (or area of each end) (ii)curved surface area

(iii)total surface area and   (iv)volume

14cm21cm

Radius of the cylinder (r) = cm

Height of the cylinder (h) = cm

Now,

(i) Area of base (area of each end) πr2 =
22
7
(2) = cm2
(ii) Curved Surface area = 2πrh = 2 ×
22
7
× × = cm2

(iii) Total Surface area = 2 × area of the base + curved surface area

  = 2 × + = cm2

(iv) Volume of cylinder = πr2h = area of the base × height

  = × = cm3
