Step-by-step explanation:

1) Diameter = 6 cm

Radius = 6/2 = 3cm

Height of the cylinder = 25-4 = 21

Volume of cylinder = pir2h

22/7 × 3 × 3 × 21

=231 cm3

Curved surface area = 2 pi r h

2 × 22/7 × 3 × 21

= 456 cm3

I'm not sure if the answer is right. Write in the comments if anything is wrong. Thank you!
