I am having a tough time with this. I'm not a math person at all. Maybe I am doing it right, but probably not. Any help to guide me in the right direction would be very helpful. Thank you.
I am trying to figure out the density of the sun if its radius expanded to 100 times its current size.
Here's what I have:
D= m/v v=4/3Pir^3 Mass of Sun: 1.99x10^30kg Radius of Sun: 695, 500
V= (4/3Pi)(695,500)^3 = 1.409x10^18
x 100, for the radius increase:
D= 1.99x10^30/1.41x10^20 = new density of 1.41x10^10 (g/km?) if per km, I changed it to cm and the number is still higher than the sun's current density....
I'm very confused!
