Answer:
19.6 cubic centimeters
Step-by-step explanation:
The ratio of two similar 3D figures' volumes is equivalent to the ratio of their corresponding lengths (whether it's width, height, length, radius, etc) cubed.
Here, we know the cones are similar, and we know the smaller radius is 2 and the larger radius is 3. Then the ratio of the volume of the smaller one to the volume of the larger one is
.
We also know the actual volume of the larger cone is 66. So, if x is the volume of the smaller cone, we have the proportion:
x / 66 = 8 / 27
Cross-multiply:
27x = 66 * 8 = 528
Divide by 27:
x = 528/27 ≈ 19.6
The answer is thus 19.6 cubic centimeters.

Answer:
Step-by-step explanation:
We are given that Twice the difference of a number and 2 is equal to three times the sum of the number and 4. And we have to tell the number.
Let the number be x
Its difference from 2 = x-2
Twice the difference =2(x-2)
Sum of number and 4 = x+4
Three times of the sum : 3(x+4)
Hence 2(x+2)=3(x+4)
2x+2×2=3x+3×4
2x+4=3x+12
Subtracting 12 and 2x from both sides.
4-12=3x-2x
-8=x
Hence the number is -8
