Question

the diameter is 42cm and the CSA is 11880cm² find weight of the cylinder.​

Answer 1

Answer:

D=42

H=24

hope this helps you

Answer 2

Given that :

Diameter of the cylinder = 42 cm

=> Radius = 42/2 = 21 cm.

And CSA of Cylinder = 11880 cm^2

As we know that :

CSA of Cylinder = 2πrh

ATQ :

2 × 22/7 × 21 × h = 11880

=> h = (11880 × 7)/(2 × 22 × 21) = 90 cm.

So, the height of the cylinder will be 90 cm.
