## anonymous 5 years ago a figure shows a rectangle inscribed in a circle. the rectangle is 4 cm in height and 3 cm along the base. how can i find the circumference of the circle?

The diameter of the circle is the diagonal of the rectangle. By Pythagorean's theorem one can find that the diaognal is 5. Now circumference of a triangle is $$\pi\cdot \text{diameter}$$. So the circumference is $$5\pi$$.
