Answer:
Perimeter is 20 area is 15
Step-by-step explanation:
The area of first area is (2t)^2*pi or whatever that variable is, I assume its t because its not clear.
The area to the second circle is t^2*pi
The area together is 80 which means
(4t^2+t^2)pi=80
5t^2pi=80
t^2pi=16
The radius of the smaller circle, t, will be 4/sqrt(pi) or 4sqrt(pi)/pi
So the larger circle has double the radius thus it will be
8/sqrt(pi) or 8sqrt(pi)/pi
This is the value, but if your teacher wants an approximate value just punch this into an calculator :) Hope it helps!

Step-by-step explanation:
I DON'T KNOW?
The quotient is given to be:
Rewrite the expression:
The quotient will be defined under the following condition:
The inequality will work if:
Hence, we can get the interval to be:
The inequality will be undefined at the point:
Therefore, the function will be defined over the interval:
