The circumferince of the circle is 2πR ;
The area of the circle is πR^{2};
Then, 2πR = 704 ;
R = 352 / π ;
πR^{2} = π × ( 352 / π )^2 = ( 352^2) / π = 123904 / π ≈ 39459.87 ≈ 39460 cm^2 ;

If the circumference of a circle is 704 cm, then the area is: 39439.87 cm.

The formula looks like this:  <span>A <span>= <span>π <span>r 2 and </span></span></span></span><span>C <span>= <span><span>2 π </span><span>r.

So, C = 704 cm and A = 39439.87 cm.

Hope I helped!

An elementary ntimesn scaling matrix with k on the diagonal is the same as the ntimesn identity matrix with _______ exactly one
Dafna11 [192]

Answer:

exactly one, 0's, triangular matrix, product and 1.

Step-by-step explanation:

So, let us first fill in the gap in the question below. Note that the capitalized words are the words to be filled in the gap and the ones in brackets too.

"An elementary ntimesn scaling matrix with k on the diagonal is the same as the ntimesn identity matrix with EXACTLY ONE of the (0's) replaced with some number k. This means it is TRIANGULAR MATRIX, and so its determinant is the PRODUCT of its diagonal entries.​ Thus, the determinant of an elementary scaling matrix with k on the diagonal is (1).

Here, one of the zeros in the identity matrix will surely be replaced by one. That is to say, the determinants = 1 × 1 × 1 => 1. Thus, it is a a triangular matrix.
