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

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

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

  11. Not the answer you are looking for?
