First time doing mensuration, can someone enlighten me on how to find the height of the hemisphere and cone?

Answer:
Step-by-step explanation:
volume=[tex]1/3\pi r^2h +2/3\pi r^3[/tex][
tex]=1/3\pi *9*4+2/3\pi *3^3[/tex]
=[tex]12\pi +18\pi[/tex]= 30 [tex]\pi[/tex] volume
Answer:
3 cm and 4 cm.
Step-by-step explanation:
The height of the hemisphere is the same as its radius, 3 cm.
The height of the cone = 7 - 3 = 4 cm.
