Circle B is shown. Line segments A B and C B are radii. The length of A B is 6. Sector A B C is shaded.
The measure of central angle ABC is StartFraction pi Over 2 EndFraction radians.

What is the area of the shaded sector?

6Pi units squared
9Pi units squared
18Pi units squared
36Pi units squared

Step-by-step explanation:

It seems your question is incomplete. A complete question is attached in figure as shown below.

we know, area of sector is given by

if  is in radian,

then, A =

or, A =

Here given,

r = 6 unit

so, A = 1/2 × (6)² × π/2

A = 1/2 × 36 × π/2 = 9π unit²

hence, option (b) is correct.

i think it is c, not positive though
