What is the area of the shaded region and the circle inside?

r=20,1m+13,2m=33,3m
A_1=\pi r^2
A_1=33,3^2\pi
A_1=1108,89\pi

What is the area of the circle inside?

A_2=20,1^2\pi
A_2=404,01\pi

What is the area of the shaded region?

1108,89\pi -404,01\pi =704,88\pi
704,88\pi \approx 704,88*3,14\approx 2213,3232\approx \underline{2213,32}

The answer: 2213,32 :)

Elden [556K]
Well, you already have the decay model, so just plug that in

\bf A=96e^{-0.000121\cdot 17000}\implies A=96e^{-2.057}
