Question

Find the area of the figure. Round to the nearest tenth.

Answer 1

To get the area of the half circle, do π r². 
Let's use 3.14 as pi. 
First square 2 to get 4 then multiply it by 3.14 to get 12.56. Since this is a half circle we have to divide it by 2 for the area: 6.28. 
Then for the triangle multiply 6 times 2 (12) then divide it by 2 to get 6. Then add the two together to get 12.28 then round to the nearest tenth to get a final answer of 12.3 m². Hope this helps!
