What is the area of the sector shown in the diagram below?

Option A is correct.

Step-by-step explanation:

Given radius of the circle, r = 8 cm

Central Angle of the shaded Sector,   = 40°

Area of Sector is given by the following formula,

Putting given values we get,

Area of Sector =

                        =

                        =

Therefore, Option A is correct.

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65

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
