Answer:
Label theta as the missing length. You are solving circle segment so use the formula
Area of Segment = θ − sin(θ)2 × r2 (when θ is in radians)
Area of Segment = ( θ × π360 − sin(θ)2 ) × r2 (when θ is in degrees)
So the answer would be 7.68
Step-by-step explanation:
the answer that i think it is 30
SA: 1575.2
(22)(22) + (26)(22) = (23.6)(22)
484 + 572 + 519.2 = 1575.2
