Need help for school please

Answer 1

Answer:

86

Step-by-step explanation:

First, we find the area of each individual polygon:

Starting with C for the half circle:

$C=\pi r^2\\C=\pi (3)^2\\C= 20$

Since it's a half circle, we divide the final product by 2:

$C=20/2\\C=10$

Next, the trapezoid:

$A=\frac{a+b}{2} h\\A=\frac{13+6}{2} (8)\\A=76$

Last, since we combined the triangle with the trapezoid, we add all the areas we've found to find the area of the entire shape:

$76+10= 86$

Hope this helped! Have a good day.
