hope this helped :>
Answer: I can't see the answers to answer the question but more importantly THIS IS A DIAGNOSTIC I CAN'T HELP YOU!!!!
Step-by-step explanation:
You haven't shared all of the question, so I'll guess that you want to find "how fast is the area of the sphere increasing?"
Area of a sphere = 4*pi*r^2
Rate of change of area of a sphere with respect to radius r:
dA/dr = 8*pi*r*(dr/dt)
Here, that would come out to
dA/dr = 8*pi*r*(2 inches / sec)
If you meant, "how fast is the volume of the sphere increasing?" you'd need to use a different equation:
V = (4/3)*pi)*r^3
and go through a similar process.
Area of polygon = (number of sides × length of one side × apothem)/2
