Answer:

The answer is 37.68 I just took the test.

Answer:

Area of the sector =  [tex]( (\frac{3\pi}{2})/2 )*(4)^2 = 12\pi = 37.699[/tex]

Step-by-step explanation:

Remember that the formula for the area of a circular sector is given by

Area of a circular sector =       [tex]\frac{\theta}{2} r^2[/tex]

Where     [tex]\theta[/tex]      is the angle measures in radians, and    [tex]r[/tex]    is the radius of the circle.

For our problem  

                       [tex]\theta = \frac{3\pi}{2}[/tex]

                       [tex]r = 4[/tex]

Therefore        Area of the sector =  [tex]( (\frac{3\pi}{2})/2 )*(4)^2 = 12\pi = 37.699[/tex]
