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.

Answer:
Estimate one digit past the smallest precisely known digit or marking
Step-by-step explanation:
To determine the last digit in any measured number : Estimate one digit past the smallest precisely known digit or marking
This is employed mostly when trying to round off a measured or calculated number to a precise number of digits and in other to determine the last digit in the given number we will have to estimate one digit past the smallest precisely known digit
Answer:
9/8, 18/16, 27/24, 36/32, 45/40, 54/48, 63/56, 72/64, 81/72, 90/80, and so on ...
Explanation:
Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 18/16 is equal to 9/8 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/8) by the same integer number, ie, multiply by 2, 3, 4, 5, 6 ...
18/16 is equivalent to 9/8 once 9 x 2 = 18 and 8 x 2 = 16
27/24 is equivalent to 9/8 once 9 x 3 = 27 and 8 x 3 = 24
36/32 is equivalent to 9/8 once 9 x 4 = 36 and 8 x 4 = 32
To convert 235/15 into mixed fraction
divide 235 by 15
so mixed fraction will be 15whole10/15
