Answer:

461.81 cm²

Step-by-step explanation:

Diameter of a big circle is 28 cm
Diameter of smaller half-circles is 28/2 = 14 cm

Shaded area = Area of big circle - area of small circle as two half-circles add up to small circle

Area formula:

A = πd²/4

Shaded area

π*28²/4 - π*14²/4 = 461.81 cm²
