Answer 2

Given :

• Radius = 7cm
• Height = 9cm

To Find :

• Total surface area of cylinder

Solution :

By using formula,

⇒ TSA of cylinder = 2πr(r+h)

⇒ TSA of cylinder = 2 × 22/7 × 7 ( 7 + 9 )

⇒ TSA of cylinder = 2 × 22/7 × 7 × 16

⇒ TSA of cylinder = 2 × 22 × 16

⇒ TSA of cylinder = 44 × 16

⇒ TSA of cylinder = 704sq.cm

•°• Hence, Total surface area of cylinder = 704sq.cm

★ Additional Information :

Total surface area Formulas :

• TSA of Cuboid = 2 ( lb + bh + hl )

• TSA of Cube = 6a²

• TSA of Cone = πr ( l + r )

• TSA of Sphere = 4πr²

• TSA of Hemisphere = 3πr²

• TSA of Cylinder = 2πr(r+h)
