Hey there! :D
When you are finding the area of corresponding sides, you square the number of the ratio of the similar lengths.
The screens a little blurry, but I'm assuming the corresponding side is represented as:

So, you would keep a and b where they are, (you would be confusing the areas if you switched it in any way) and then just square the variables.
"C" is the best answer. I hope this helps!

Answer:
r = 2cm
h= 18cm
surface area of cylinder = 2πr ( r + h)
= 2*22/7*2(2+18)
= 125.714cm²
volume of cylinder = πr²h
22/7*(2)²*18
=226.29cm³
Answer:
6:15 and 8:20 are examples of additional equivalent ratios.
Step-by-step explanation:
The table is:
<u>Books (x) Cost (y)</u>
2 5
4 10
From the table, the ratio Books : Cost is 2:5 or 4:10. Equivalent ratios are obtained, using a graph, from the plot of the line that pass through these two points. In the figure attached, this line is shown. There, it can be seen that ratios 6:15 and 8:20 are equivalent to those from the table.
