I have no idea how to do this problem i dont know what a is
Hi there!
First, let's find the proportion of the radius' and set it equal to the proportion of the heights:
12/10 = 30/25
Next, we'll cross multiply. If the numbers are the same, then the solids are similar.
300 = 300
The solids are similar! The scale factor from the larger solid to the smaller solid is 6/5 or 1.2. The scale factor from the smaller solid to the larger solid is 5/6.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Each number is the number before it multiplied by 1.1
And since it is multiplied, there is a common ratio and so it is a geometric sequence.
3 x 1.1 = 3.3
3.3 x 1.1 = 3.63
And it goes on.
Hope this helps :)
.5 is really just 1/2 as a fraction so:
112 1/2 is fraction form
