Question

Help with this problem please!

Answer 1

the area of the blue region is equal to :

area of the circle - area of the triangle



the area of the circle is 28.26

`(3 * 3) * 3.14 = 9 * 3.14 \\ = 28.26`

the area of the triangle is 9.45

`((1.1 + 3.4) * 4.2) / 2 \\ = (4.5 * 4.2) / 2 = 18.9 / 2 \\ 9.45`


so the area of the blue region is

`28.26 - 9.45 = 18.81`


the final answer is 18.81



good luck
