Okay well for example--if the radius was 6 and the height was 12 the volume would be 1357.17, and if you multiply those by 1/3 which is the same as dividing it by 3, then you would have a radius off 2 and a height of 4, and the volume of that is 50.27, sooooooooo well the volume of the cylinder would decrease by like 26 to 27 times.

Answer:

The volume is multiplied by 1/27.

Step-by-step explanation:

Let the radius equal r and the height equal h for the original cylinder.

The volume of a cylinder with radius r and height h is V=πr2h.

Therefore,  the volume for the original cylinder is πr2h.

The new cylinder has dimensions that are one third those of the original cylinder: the radius equals 1/3r and the height equals 1/3h.

To calculate the volume of the cylinder, substitute the new values into the formula for volume of a cylinder.

V=π⋅(r3)2⋅(h3)

Simplify.

V=1/27πr2h

The new volume is 1/27πr2h.

If the radius and the height of the cylinder are multiplied by 1/3, the volume is multiplied by 1/27.

Therefore, the new volume is the original volume multiplied by 1/27.

Suppose A is an invertible n×n matrix and v is an eigenvector of A with associated eigenvalue 4. Convince yourself that v is an
mote1985 [20]

The eigenvector of matrix A4 is 4096.

The eigenvalue of the matrix A-1 is 1/8.

(A+4I) has an eigenvalue of 12.

40 is the eigenvalue of 5Av.

The collection of scalar values known as the eigenvalues of a matrix are connected to the set of linear equations that are most likely contained within the matrix equations.

The eigenvectors are also known as the characteristic roots.

If the matrix A's eigen vector v is linked to an eigen value.

Av then equals lamda v.

The fact that v is an eigen vector of A with the value eight is assumed.

hence, Av = 8v.

We must determine the eigenvalue of A4.

A4*v equals A3(8v) = 84*v equals 4096v.

As a result, the eigenvalue of A4 is 4096.

Suppose A has an eigenvalue of 8. The eigenvalue of A-1 is thus 1/8.

It is calculated that the eigenvalue of (A+4I) is (A +4In)v = Av + 4v = 8v + 4v =12v.

(A+4I) has an eigenvalue of 12.

The value of 5Av's eigenvalue is 5Av = 5*8v = 40v.

40 is the eigenvalue of 5Av.
