Find the area of the irregular figure (use 3.14 for pi). SHow your work. Round to the nearest tenth.

Triangle with a semi-circle on it. The triangles height is 4.8ft and the circle's diameter is 3.6ft.
Every time I do my work I keep getting 12.3 and I have no clue if I'm doing anything wrong
Answered by Somebody Person
Well the area formula for a triangle is A=bh/2 plus the area of the semi circle which is A=3.14r^{2}/2
Answered by Baby_Banana
3.6 divided by 2
1.8

3.14x1.8x1.8
10.2

10.2 divided by 2
5.1

1/2 4.8x5.1
2 divided by 24.5
12.3
This is my work
Answered by scott
the triangle is ... 1/2 b h = 1/2 * 3.6 * 4.8

the semi-circle is ... 1/2 π r^2 = 1/2 * 3.14 * 1.8^2
Answered by Baby_Banana
So it would be 12.2?
Answered by Somebody Person
What you do is 4.8*3.6=A then divide your answer in half which is the area of the triangle than to find the area of the semi circle you do 3.14*1.8^{2}=A then divide that in half than add the two together then round to the nearest tenth.
Answered by Baby_Banana
Ohhhh, so it would be 13.7! Thank you very much
Answered by Monica
I’m confused. Please show your work. Mine keeps getting 12.2
Answered by Helper
Your correct Baby_Banana! It's 13.7 or 13.73. I only need help with the last one. I was never good with graphs.

@Helper
Wait, I got 13.72! Not 13.73, is there something I’m doing wrong?
Answered by Huh
Where do you get the 1.8 from
Answered by Duddeeee
@Monica

You then have to round 12.2 to the nearest 10th, which would end up being 13.7

If any of yall get 13.72 the answer will still be 13.7 because it is not 5 and over so you round down the same with 13.73 it is not 5 and over so you round down.

Yall can thank me later!!!!!!!!!!!!
