This is circle as you observed
2 x 22/7 x 7
Part B a bit difficult
The angle subscribe is 120
Therefore
120/360 x 22/7 x 7 x 7 is the area of fan
Minus the area of triangle 120
Which is the equal triangle with side of 6, that is 6 x 6 /2
The triangle area is 63, which the non shaded area is 1/3 of 63 if splitted with the “Mercedes” symboled
Therefore
1/3 x 22 x 7 - 3 x 6 - 21
