Problem: the height of a cylinder is 60 cm and the diameter of its base is 5 cm . the total surface area of the cylinder is
Rationale: given h = 60 cm and r = 5 / 2 cm total surface area = 2 π rh + 2 & pir ( power 2 ) = 2 π r ( h + r ) = [ 2 × 22 / 7 × 5 / 2 × ( 60 + 5 / 2 ) ] cm ( power 2 ) = [ 44 / 7 × 5 / 2 × ( ( 120 + 5 ) / 2 ) ] cm ( power 2 ) = 22 / 7 × 5 × 125 / 2 cm ( power 2 ) = ( 55 × 125 ) / 7 cm ( power 2 ) = 6875 / 7 cm ( power 2 ) = 982.14 cm ( power 2 ) answer is c .
