If the heights of two circular cylinder are in ... - JAMB Mathematics 1990 Question

(\frac{h_1}{h_2}) = (\frac{2}{3})

h₂ = (\frac{2h_1}{3})

(\frac{r_1}{r_2}) = (\frac{9}{8})

r₂ = (\frac{9r_1}{8})

v₁ = (\pi)((\frac{9r_1}{8}))₂((\frac{2h_1}{3}))

= (\pi)r₁ 2h₁ x (\frac{27}{32})

v = (\frac{\pi r_1 2h_1 \times \frac{27}{32}}{\pi r_1 2h_1}) = (\frac{27}{32})

v₂ : v₁ = 27 : 32
