Acylinder shaped water tank has a diameter of 8 m and a height of 20 m. what volume of water does the tank contain when it is 60% full? use 3.14 to approximate pi. enter your answer as a decimal to the hundredths place in the box. m³

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
