Question

a solid consists of a cone attached to a hemisphere . calculate the volume of the solid if diameter of the hemisphere is 3cm and the overall height is 7cm

Answer 1

Step-by-step explanation:

solid consists of a cone attached to a hemisphere.

Calculate the volume of the solid if the diameter of the hemisphere is 3cm and the overall height of the object is 7cm.

:

The radius of the cone & the height of the hemisphere: 3/2 = 1.5 cm

The height of the cone: 7 - 1.5 = 5.5 cm

:

Volume = volume of cone + volume of hemisphere:

V = (1%2F3*pi%2A1.5%5E2%2A5.5) + (1%2F2*4%2F3*pi%2A1.5%5E3)

V = (1%2F3*pi%2A1.5%5E2%2A5.5) + (2%2F3*pi%2A1.5%5E3)

V = 12.959 + 7.069

V = 20.28 cu/in
