Question

The volume of a right circular cone is 20096cm cube if the diameter is 40cm find the slant height of cone and csa (use pie:3.14)

Answer 1

Answer:

I'd diameter d=40cm

then radius=r=d/2=20cm

let slant height is h cm

given volume of cone v=20096cm cube

1/3*pi*r^2*h=20096

1/3 *3.14* 20*20*h=20096

3.14*400*h=60288

h=48cm

therefore slant height =48cm
