Question

AC and BD are two perpendicular diameters of a circle with center O. If AC = 16 cm, calculate the area and perimeter of the shaded part.
$(take \: \pi = 3.14)$
​

Answer 1

Answer:

Given radius of circle is 8 cm.

Ar. Of shaded part = 1/2πr2 = ½ × 3.14 × 82

= 100.48 cm2

Perimeter of the shaded part

= πr + 4r

= 3.14 × 8 + 4 × 8

= 25.12 + 32

= 57.12 cm
