What is the area of the blue shaded region ?
please help

125.66

Step-by-step explanation:

11cm squared times pi =380.13

9cm squared times pi =254.47

380.13-254.47=125.66

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

only 10/60 isn't equivalent

hope this : )
