The area of the circle is 
Step-by-step explanation:
we know that
The area of a circle subtends a central angle of
radians
so
By proportion find the area of the circle

We will calculate this by using ratios and because these two triangles are similar, which is very important.
Explanation:
We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.
9 : 21 = 18 : x
x = (21*18)/9
x = 378/9
x = 42.
The correct answer is B. 42.
