Question

Help i need an answer please dont answer if you are not positive

Answer 1

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 :)
