1.the radii of two circles are in the ratio of 3 to 1. find the area of the smaller circle if the area of the larger circle is 27 sq. in.

3 in²

Step-by-step explanation:

The linear ratio = 3 : 1, hence

The area ratio = 3² : 1² = 9 : 1

let x be the area of the smaller circle, then

= ( cross- multiply )

9x = 27 ( divide both sides by 9 )

x = 3

Area of the smaller circle = 3 in²

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
