The circumference of a roll of party streamers is 10 inches. the circumference decreases by 4 inches after you use the streamers to decorate for a holiday party. find the diameter of the roll after the decrease. round your answer to the nearest hundredth.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

where is the graph, sweetheart?
