Question

Find the total surface area of a closed cylindrical drum if its diameter is 50 cm and height is 45 cm. (π = 3.14)

Solution

Diameter = 50 cm
Radius = 25 cm
Height = 45 cm
Total surface area = 2 π r (h + r ) 

                              = `2 xx 3.14 xx 25 (25 + 45)`

                              = 10990 sq cm

Thus, the total surface area of the closed cylinderical drum is 10990 sq cm.

  Is there an error in this question or solution?
