I'm still working on Part B.

that looks right for part A

For the growing circle, The Area is a function of the radius, and the radius i a function of time...

Area----->Radius---->time

use t=10 min in your Area function

it doesnt matter, try it both ways, same answer

Calculating A(r(t)) is the same as first finding r(t) then using that in A(r)

Right, and the same answer if you use A(r(t))
28.26 * 10^2 = 2826

So my work is right?

yes, looks good

Thank you so much! I really appreciate your help! :)

no prob, goodluck

what was part A?

π(3t)^2
^ That equation will help you find the answer.
You multiply 3.14 times 3^2 times t^2

So it'll look like:
(3.14)(9)(t^2)
Then multiply.
The answer is 28.26t^2

Wait can you please explain what is part A and B? please
