Question

The curved surface area and volume of a cylindrical pillar are 264msq. And 396mcube. Find the diameter and height of the pillar.

Answer 1

Answer:

Step-by-step explanation:

CSA=264m²

2*22/7*r*h=264m²

r*h=42

r=42/h...............(I)

Volume =πr²h=396m³

22/7*(42/h)²*h=396

h=14m

Now put in (I)

r=42/14

r=3m

Since diameter is twice the radius so 2r=2*3=6m
