Answer:
The expression provided by the area (square meters) is given by:
.
Step-by-step explanation:
The area of the algae colony is a function of the radius r (meters), so
.
The radius of the circle formed by the algae colony is a function of time t (in minutes), so
. So,
[Substituting the expression for radius]

Then the expression provided by the area (square meters) is given by:
.
The answer is 2/8. Hope this helps.
if you take the radius of the first and second sphere you find that they are doubled there fore the volume changed at a rate of 2 squared because 2 is what the radius was multiplied by going from the second sphere to the first so you would square what the sphere was multiplied by there fore making your answer: the volume is compares with 2 squared
