37. r2= 2r1V₁ : V₂ = (r₁)³ : (r₂)³
V₁ : V₂ = (r₁)³ : (2r₁)³
V₁ : V₂ = 1 : 8
38. d₁= 1/3 d₂
d₂ = 3 d₁
r₂ = 3r₁
V₁ : V₂ = (r₁)³ : (r₂)³ = (r₁)³ : (3r₁)³
V₁: V₂ = 1 : 27
39. r₂ = 1/2 r₁
r₁ = 2r₂
V₁: V₂= (r₁)³ : (r₂)³ = (2r₂)³ : (r₂)³
V₁: V₂ = 8 : 1
40. t= 2r
Vbola : Vtabung = 4/3 π r³ : π r² t
Vb : Vt = 4/3 π r³ : π r² (2r)
Vb : Vt = 4/3 : 2 = 4 : 6 = 2 : 3
