Question

Find the area of shaded part​

Answer 1

• 461.81 cm²

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
