The area of a circle is 0.1256 square meters. What is the circle's diameter?
Use 3.14 for a.

0.2

Step-by-step explanation:

A = 0.1256 given

A = (3.14)r^2 formula for area of a circle

0.1256 = (3.14)r^2 substitute

0.04 = r^2 divide both sides by 3.14

0.2 = r square root of both sides

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 answer to this question is 3/19
