First option: 14.0 cm^2
Area of semicircle + area of triangle
1/2(pi)(r^2) + 1/2(b)(h)
1/2(3.14)(1.5^2) + 1/2(3)(7)
3.53+ 10.5
14.03 cm^2
Observe.
6/2(1+2)
6/2(3)
6/6
1
Thus, the answer is: 1

Answer: 231
Ok done. Thank to me :>
Split it up into compound shapes, calculate the areas individually and then add and subtract the relevant quantities.
For instance, the shape in part a can be split up into a quarter circle, a trapezium and a half circle. I have included a diagram that may be of assistance in understanding what I mean but I leave the calculations to you. (They're quite easy when you split the shape up anyway)
As x → -∞, y → -∞
as x → ∞, y → ∞
