Step-by-step explanation:

Radius = 4ft

Angle of sector = 3 pi/2

convert to degree = 3 pi/2 × 180/ pi = 270°

Pi = 3.14

Area of sector = Angle of sector/Angle of circle × pi × r²

= 270/360 × 3.14 × 4²

= 0.75 × 3.14 × 16

= 37.68 ft²

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
