Answer is 4:2 (choice B)

AB is 4 units while A'B' is 2 units. The ratio of the sides is simply gluing these two numbers together with a colon symbol in between to get 4:2. We can reduce this to get 2:1, but your teacher has decided not to do this.

Can anybody do all of number 1??

MAXImum [283]

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
