Hello, I made the following code based on the following physics problem:
"A sphere of metal has a radius of 6.7 cm and a density of 9.27 g/cm^3. What's the mass of the sphere?".
The program runs error-free, except that it gives me a result (mass) of 8758.99 grams. The result using my TI 89 calculator is 11678.7 grams. I believe the TI 89 must be correct. What could be the problem?
Thanks a bunch!

double radius, density, mass, volume, pi;
cout<<"Enter radius: \n";
cin>>radius;
cout<<"Enter density: \n";
cin>>density;
pi=3.14159265;
volume=(4/3)*pi*pow(radius,3);
mass=density*volume;
cout<<"The mass of the sphere is: "<<mass<<" grams.\n";
return 0;
