Find area of shaded regions ​

Mathematics
1 answer:
emmasim [6.3K]3 years ago
6 0

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

Ierofanga [76]

Common ratio = 4/2 = 2

16/8 = 2

But -32/16 = -2.

The ratio is not constant, hence it is not a geometric.

D. The sequence is not a geometric sequence.</span>
