You have a triangle and a semicircle 
The triangle area is 

Base x height/2

And semicircle is

πr^2/2. 

Try it

gabbyalicorn · Answer

so 12 is the base and 16 is the height?

gabbyalicorn · Answer

Okay, so I am going to go with that...
12 x 16 = 192 $$192 \div 2$$ = 96.

gabbyalicorn · Answer

then 3.14x 4 (i doubled it cuz it had the ^2)

gabbyalicorn · Answer

3.14x 4 = 12.56

πr^2/2
π(10)^2/2
π.100/2

gabbyalicorn · Answer

wait so are these all separate problems?

gabbyalicorn · Answer

1. 3.14
2. 31.4
3. 157 
???????????

anonymous · Answer

No,mlook at the answers, it doesn't replace π by 3.14, so the semicircle are is 50π and the triangle 96
