Greeting people,

 

Problems of the day:

 

For what nonzero value of r, the radius, is the circumference of a circle numerically equal to its area?

 

Thanks!

Set the formula for circumference equal to the formula for area. Solve.

pi*r^2=pi*d

r^2=d

2^2=4

the answer is 2...this wasn't advanced :\

took me like 5 seconds to determine what formula to do, 3 seconds to figure out how to do it and maybe 5 seconds to do the work

Try not to gloat too much over things like that. What may seem quite trivial to you can be very advanced to someone else. I daresay you'd probably find some of the metric spaces work I'm doing at the moment a bit "advanced"

perhaps i overreacted. i do not have a particular affinity for mathematics:\

perhaps the whole "experts only" thing was the thing that set me off

No problem, just try and bear it in mind.
