2πr3=πr2h for h A manufacturer can save money by making a can that maximizes volume and minimizes the amount of metal used. For a can with radius r and height h, this goal is reached when 2πr3=πr2h.

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

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

c. side angle side. u shares the same sides
