Question

The given figure shows the cross-section of a cone, a cylinder and a hemisphere all with the same diameter 10 cm and the other dimensions are as shown. Calculate: the density of the material if its total weight is 1.7 kg 

Answer 1

Total weight of the solid = 1.7 kg

Total volume of solid = 1.12 gm/cm³

∴ Density = `(1.7 xx 1000)/(1519.0476)` gm/cm³ = 1.119 gm/cm³ 

⇒ Density = 1.12 gm/cm³
