Question

Write the area of the coloured region in the
given figure, in factorised form.
​

Answer 1

Area of the coloured region = Area of the circle - Area of SQUARE

Step-by-step explanation:

Area of the circle = π r²

Area of SQUARE = a2

area of the coloured region = π r² - a2

area of the coloured region = π (15 × 15) - (9 × 9)

area of the coloured region = π 225 - 81

area of the coloured region = 225π - 81
