I suggest maybe searching up the equation or looking back and your notes. Really hoped this helped you out i will try my best to try to solve if you still cannot find your formulas:)
Answer:
38.5 cm^2
Step-by-step explanation:
Area(shaded) = Area(large semicircle) - area(2 small equal semicircles)
= Area (large semicircle) - area (small circle)
= π(7)² x 1/2 - π(7/2)²
22/7 x 7 x 7 x 1/2 - 22/7 x 7/2 x 7/2
= 77 - 38.5
= 38.5 cm^2
