What's the inverse of a 2x4 matrix?

balandron [24]

Mxn Matrices do not have an inverse solution for m ≠ n, so your 2x4 will not have a solution.

<span>Generally, inverting matrices is done through finding the determinant of the square matrix and then performing an operation on the matrix based on the size of the matrix. </span>

<span>Wikipedia has a good article on Matrix inversion, take a look there for more information.</span>

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 :)
