Question

Can anybody do all of number 1??

Answer 1

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×
`(h)/(3)`

Square Prism= 2×a²+4×a×h a²×h

↑a=base edge

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
