प्रश्न
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
उत्तर
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
