These cones are similar. Find the volume
of the smaller cone. Round to the
nearest tenth.

19.5

Step-by-step explanation:

The Volume of a cone is h/3(r²)

That means, for the larger cone,

66=h/3(3²)()

66=h/3*9

66/9*3=h

h=7, so the height of the larger cone is seven

Since the cones are similar, it has to have the same ratio. 7/3 of 2 is 4.6666.  So the height of the smaller cone is 4.66666.

Putting that in the formula,

V=(4.66666/3)(2²)

V=1.555555*4*

V=19.547

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
