Question

Need help for school please

Find the area of the figure below, composed of an isosceles trapezoid and one semicircle. Round to the nearest tenths place.

Answer 1

86

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=(a+b)/(2) h\\A=(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.
