Question

the vertical height of a right circular cone is three times its diameter and its volume is 54 pie cm cube. find its height.​

Answer 1

Answer:

cone:

h=3r,r=h/3

vol=54πcm3

1/3πr^2h=54π

1/3xπx(h/3) 2xh=54π

1/3πxh^2/9xh=54π

πh^3=54πx3x9

h^3=54πx27/π = 54x27

h^3=1458

h = 3 v1458=11.34cm
