Right Circular Cylinder:
Diameter = 40 cm
Radius = 20 cm
Height = 55 cm
TSA of a cylinder = 2πr(h+r) sq.units
= 2 × 22/7 × 20 ( 55 + 20 )
= 2× 22/7 ×20(75)
= 3000 × 22/7
= 3000π sq.cm (or) 9428.57 sq.cm
CSA of a cylinder = 2πrh sq.units
= 2 × 22/7 × 20 × 55
= 2200 × 22/7
= 6914.28 sq.cm (or) 2200π sq.cm
