Question Given :
- find CSA of a cylinder radius is 100cm, height is 21cm
Required Solution :
Values Given to us :
- radius of cylinder = 100cm
- Height of cylinder = 21 cm
Required Diagram :
Formula Used Here :
- 2 πrh
Putting Value In Formula :
- 2 × 22 / 7 × 21 × 100
- CSA = 2 × 22 × 3 × 100 cm
- CSA = 44 × 300 cm
- CSA = 13200cm²
CSA Cylinder 13200 cm²

Radius of cylinder (r) = 100 cm
Height of cylinder (h) = 21 cm
To find -
The C. S. A. (Curved Surface Area) of the cylinder
Solution -
C. S. A. of cylinder = 2πrh
Hence C. S. A. of cylinder = 13,200 cm² (1.32 m²)
