Answer:
MARK BRAINLIEST....
Step-by-step explanation:
d= 18cm
r = 9 cm
We can also put the formula of segment.
As we are well concerned about the formula of segment. i.e.
πr²∅/360 - 1/2r²Sin∅
After putting the values, we get
22 × 9 × 9 × 90 _ 1 × 9 × 9 × 1
7 360 2
11 × 9 × 9 × 1 _ 81
7 2 2
= 891 _ 81
14 2
= 891 - 81 = 810
14 14
= 57.85 cm²
But according to question, there are 4 segments...
Area = 4 × area of segment
= 4 × 57.85
= 231.42
