SUMMARY
The constant density of a solid sphere with a radius of 10 cm and mass of 15 kg is determined using the equation p = po * e^(r/R). By substituting r = 0 into the density formula, the value of po is calculated to be 3580 kg/m³. The discussion emphasizes the necessity of integrating the density equation to find the total mass and subsequently derive the constant density.
