all you have to do is add 2.09 to itself until it gets to 22.5
2.09 x 10 = 20.9
2.09 x 11 = 22.99
so, 2.09 goes into 22.5 ten times
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.

What ..........................................................................
Any decimal that repeats can be expressed a a rational number with integer numerator and denominator...
This is the procedure to finding the rational fraction
x=0.111..... then you multiply this x so that it is greater than 1 but still has the same repeating decimal portion, here we just need to multiply by 10 so:
10x=1.111....
Now you subtract the repeating decimal from the multiple of x...
10x=1.111...
- x=0.111...
9x=1 now just get x by itself..
x=1/9
This procedure works for any repeating decimal...
