Water is leaking onto the floor creating a circular pool with an area that increases at a rate of 3cm^2 per minute. How fast is the radius of the pool increasing when the width of the puddle is 20cm? And they wonder why nothing ever gets done around the house :)

    do tell, why would you "need" an answer to a statement I posted on my facebook account? That seems more of a want then a need.

    Oh, it is a very simple calculus problem, but it's been so long since i've done it someone can check on me. \[a =pir ^{2}\]\[dA =2pir(dr/dt)\]

    sath came up with so far ; is copied a statement from my facebook page and claims it as his own .... the first part is from a library textbook that I found intriguing, the last bit was my thoughts about why someone would not just clean it up to begin with ;)

    There seems to be an admission, the mystery remains how Sathi would come across your page. Anyway above, Sathi plug in values for r=10 and dr/dt = 3. That gives you the area. Now you want to know when pool is 20 which is really when radius is 10. I don't know Amistre tell us how to do your problem.

    Well, you derive the Area of a circle with respect to time; then solve for dr/dt knowing that dA/dt = 3

    A = pi r^2 A' = 2pi r r' r' = A'/(2pi r) r' = 3/(2pi 10) if I recall it from so long ago lol

    Let me go to your page. There has been so much debate. First it was argued Amistre is a woman. Then some kid said yesterday, Amistre is my Dad. May be I can solve that mystery on Facebook.
