Answer:
A = 121 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi*r
22 pi = 2 * pi *r
Divide each side by 2 pi
22 pi / (2 pi) = 2 pi r / (2pi)
11 = r
Now find the area
A = pi r^2
A = pi (11)^2
A = 121 pi in^2
I'm assuming the given log equation is 
If so, then the exponential form is 
This is because the general form
transforms into 
For both equations, the 'b' is the base.
10 cancels out so its 5/3 :) Rate Me plz <span />
