7 0

Answer:

b = 57.6

Step-by-step explanation:

23 +3x +13 +2x=180

add the x's

5x

add the others

23+13=36

subtract 36 on both sides

36-36=0

180-36= 144

now get your 5x and divide by 5 on both sides

5/5 cancels out

144/5= 28.8

x= 28.8

now to find b

2·28.8= 57.6

to find 3x do the same

3 · 28.8 = 86.4

now double-check your answer by adding them all up and seeing if it = 180

57.6+86.4+36=180

Answer:

You use the formulas for the shapes

Cylinder= 2×π×r×h+2×π×r²               π×r²×h

Cone= \pi*r(r+\sqrt{ h^{2} +r^{2}} )           π×r²×\frac{h}{3}

Square Prism= 2×a²+4×a×h                       a²×h

                            ↑a=base edge

Step-by-step explanation:

                           Surface Area  Volume

Cylinderical Head   ≈282.74                   ≈314.16  

Conical Hat                     ≈170.13                     ≈78.54

Right Cylinder Torso      ≈471.24                     ≈785.4  

Right Cylinder Arm         ≈56.55                      ≈25.13

Square Prism Leg           =224                           =192
