PLEASE HELP WITH THIS DIFFERENTIAL EQUATION!!!!

GULCH_OF_ROT

Please help:
Does any one know how to solve this differential equation?

A spherical ice-cream ball of initial diameter 12 cm melts at a rate that is proportional to its surface area.
At this diameter it is melting at a rate of 6 cm/min.
Write the differential equation to model this situation.
Find its solution.
And predict when the ball will all be melted.

wtf is this shit

the problem depends, what flavor is the spherical ice cream?

Good luck...I had to withdraw for Pre-calc...so that's all alien to me.

Ok, I'm going to try to see if I can help....it's been a while since I took Differential Equations.

Surface area of a sphere = 4*pi*r^2. You know diameter, so subbing in D/2 for r gives you

SA = pi*D^2

At t = 0, dD/dt = -6 and D(0) = 6....hmm.

MY TEACHER GAVE ME A HINT AND SAID THAT Y SHOULD BE = TO VOLUME

Ah, well I can do that too. I'll redo it when I get back from class.

Just when you think you have the answers, Jaycup buys new questions.

Jay should just bribe Gulchs teacher into passing him.
