I need help w this !

I'm not really sure about the ANSWER but

Step-by-step explanation:

on a.) you can split it and take the middle out and that answer would be 60. then you could put the pieces that are left put them together and do the circle formula i hope that helps

I dont exactly know but for a i would say 34 because what we are doing to find area to a composite shape so what i did was add 15 + 15 + 4 and for b i would say do the same but multiply the two numbers for the bottom half because thats an actual shape and you will get 16

hope this helps
