An empty swimming pool needs to be filled to the top. the pool is shaped like a cylinder with a diameter of 6 m and a depth of 1.2 m . suppose water is pumped into the pool at a rate of 17 m3 per hour. how many hours will it take to fill the empty pool? use the value 3.14 for π , and round your answer to the nearest hour. do not round any intermediate computations.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

the answer is ! ?
