Answer:

B

Step-by-step explanation:

<u>it is important to note that 40/8 = 5. </u>

A real number is one that can be found on the number line, and 5 can be.

Nana76 [90]

Answer:

.83333333 or 5/6

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
