Question

Find the area of the white region in the diagram shown.

Answer 1

Option 4

Explanation:

Area of shaded region = Area of the circle - Area of the shaded triangles

Area of the circle = πr²

r = Radius of the circle

Therefore, area of the circle = π(4)²

= 16π

Area of the given triangles =
`2[(1)/(2)(\text{Base})(\text{Height})]`

= Base × Height

= (4 × 4)

= 16

Area of the shaded region = 16π - 16

Option 4 will be the correct option.
