Find the circumference of the circle. 10.1 in
Hint: C = xxd
x= 3.14

A.15.857 in
B.31.714 in
C.63.428 in
D.13.24 in

Step-by-step explanation:

c=3.14×3.14×10.1

=99.58196

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
