(1) Find the area of minor sector AOB

(2) Find the perimeter of the circle

to find answers we first need the radius , in this case we find it using arc length

arc length =

18.07=

18.07=

18.07x360=

r=

r=9cm

1) area of minor sector=

                                     =

                                     = 81.29

2) perimeter of the circle is the same as its circumference which is

circumference=

                       =

                        =56.55cm

Step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
