Answer:
170
Step-by-step explanation:
your welcome np 8 hope you appreciate it
You can start by drawing a number line and labeling it with eighths. ( 1/8, 2/8, etc.) Then you can place a dot on 3/8 and 5/8. From there, it's clear to see that 5/8 is greater than 3/8.
In order to find what fraction describes this percentage, you first need to know that no matter what percentage you are working with, if you want to convert it into a fraction, put the 35 as the numerator and 100 as the denominator. If you still don't know what I mean, 35 at the top of the fraction and 100 at the bottom. Like this; 35/100. Then, you can simplify it by finding a common multiple between 35 and 100. For example, 5 can be divided into 35 and 100. 35 divided by 5 is 7 and 100 divided by 5 is 20. Your result is 7/20, which can further no more be simplified because there are no more common multiples between the two numbers.
We know that the volume of a sphere of radius r is given by
Now, we have been given the initial volume was 4,188.79 cubic centimeters. Let us find the radius at this time.
Substituting the value of volume in the above equation, we get
Now, the final volume is given by 14,137.167 cubic centimeters. Thus, we have
Now, let us find the surface areas for these two radii.
For 
Surface area is given by
Similarly, for
Therefore, the increase in the surface area is given by
Hence, the average rate at which the surface area is changing is given by
Therefore, the average rate at which the surface area is changing is given by 130.8 square centimeters per second.
