Q2 of 12 Page 110

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

Total surface area of cylinder(TSA) = 2πr(h+r)


Here,


h = 45 cm


Total Surface Area = 2 × 3.14 × 25(45+25)


= 10990 cm2


Total Surface Area of Cylinder is 10990 cm2
