Hello!

Question 1:
We have to put the ratio of the volumes

It is 27:125 ratio

This can be put as 27/125

We can multiply this by 63 to get the unknown surface area

This gives us 292

The answer is 292in^2

Question 2:
We have to find the ratio of the radius

3.1 : 6.2

We can see that they multiplied the first balloon by 2 to get the second

To find the missing volume we do 125 * 2 = 250

The answer is 250cm^3

Hope this helps!

8 units is the answer.

Step-by-step explanation:

Pythagorean theorem can be written as,

$d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(9-9)^2 + (-7-1)^2}\\\\d=\sqrt{(0\\)^2+(-8)^2} \\\\d=\sqrt{64} \\\\d=8$
