Answer:

The appropriate answer is "108π unit²".

Explanation:

The given values are:

Angle,

[tex]\Theta = 270^{\circ}[/tex]

Radius,

r = 12 units

Now,

The area of the sector of a circle will be:

=  [tex]\frac{\Theta}{360}\times \pi\times (r)^ 2[/tex]

On substituting the given values in the above formula, we get

=  [tex]\frac{270}{360}\times \pi \times (12)^2[/tex]

=  [tex]0.75\times \pi\times 144[/tex]

=  [tex]108\pi \ unit^2[/tex]
