First, plug in the radius and height into the equation. V=1/3pi*4^2*9 Next solve. 3.14 x 16 x 9 = 452.16 Then you need to divide 452.16 by 3 to get 150.72
12 is the answer because when you add the green and blue you get 5 and 5×4= 20 so you multiply the blue by 4 and the green by 4 and add them together which = 20. so 3×4=12 and 2×4=8 so your answer is again 12
