Question
The diameter of the base of a cylindrical vessel is 30
cm and its height is 56 cm. Find its curved surface area (in cmΒ²).Solution
Curved surface area = 2 Οrh Given Diameter = 30 cm, so radius r = 15 cm Height h = 56 cm Substitute these values: CSA = 2 Γ 15 Γ 56 Ο CSA =1680 Ο Approximating Ο as 22/7 CSA= 1680 Γ 22/7 Β =240Γ22=5280cmΒ²
