I would say that this would be an observational study, because Soo Jin isn't forcing anyone to participate (an experiment) and he has no control over any of the variables in this situation (experiment or survey).

756π cm^3.

Step-by-step explanation:

Volume of the cone

270π = 1/3 π r^2 h

270π = 1/3 π r^2 * 10

r^2 = 270 / ( 10/3 )

r^2 = 81

r = 9 cm.

So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3

= 486π cm^3.

So the volume of the whole solid = 270π + 486π

= 756 π cm^3.
