I can answer this but I need more terms
475.82
is the answr i think
Rectangle = 18 x 6 = 108
Circle: 3.14 x (3)^2 = 3.14 x 9 = 28.26
<span>semicircle: 28.26 / 2 = 14.13
</span>
108 + 14.13 = 122.13
answer
122.13 cm^2
If you're just integrating a vector-valued function, you just integrate each component:
The first integral is trivial since .
The second can be done by substituting :
The third can be found by integrating by parts:
