Find the diameter of the circle by finding the diagonal of the rectangle, using the Pythagorean Theorem. (The diagonal is the hypoteneuse of a right triangle with sides 3 and 4.)
Once you realize the diameter, it's easy to figure the circumference, which is the diameter times pi.

find the diagonal of the rectangle first. then use the diameter to solve the circumference... 2(pi)r where radius = 1/2 diameter

diamiter is 5 (3 squared is 9, 4 squared is 16. 9+16=25, square root of 25 is 5. or u could use a tip my algerbra teacher told me. if the two smaller sides r 3 and 4, or any multiples of it (they have to have the same other number though, like 6 and 8, or 9 and 12) then the other number will be 5, or 5 multiplied by the same thing as the other numbers), circumfrence is equal to pi*diamiter, pi is equal to 3,14. u figure it out.

First figure out the length from one corner of the rectangle to the other (Pythogorean theorem). That's your diameter. Work from there.
I won't do your homework for you but I'll give you a boost.

The diameter is 5, figure it out from there.
