Given

There is a cylinder with dimensions :-

• Diameter = 28 cm

• Radius = Diameter / 2 = 28 / 2 = 14 cm

• Height = 40 cm

To Find

Curved Surface Area, Total Surface Area and Volume of given Cylinder.

Formula for a Cylinder

Curved Surface Area

2πrh

Total Surface Area

2πr( r + h )

Volume

πr²h

where

• r = Radius of Cylinder

• h = Height of Cylinder

Solution

Curved Surface Area ( CSA )

2πrh

2π( 14 cm )( 40 cm )

2 × 22/7 × 14 × 40 cm²

3520 cm²

Total Surface Area ( TSA )

2πr( r + h )

2 × 22/7 × 14 × ( 14 + 40 ) cm²

4752 cm²

Volume ( V )

πr²h

22/7 × ( 14 )² × 40 cm³

24640 cm³

Answer

So,

• CSA = 3520 cm²

• TSA = 4752 cm²

• V = 24640 cm³
