- Assume a ice ball melts so that volume decreases proportionately to its surface area. It takes eight hours to melt down to 1/8 of its original volume. How much time does it take to melt completely?
- Relevant Equations
- -
So to begin this question, I do know that volume =4/3 pi r cubed, while the surface area) 4 pi r squared.
I will like to clarify some things about the question:
1) does the first sentence means dv/dt is proportional to 4 pi r squared?
2) given the second sentence how am I able to construct an equation out of the values given to me?
Thanks
