Answer:
44
Step-by-step explanation:
954/22=43.3636363636
The area of a circle is given by
whereas the circumference is given by
If we want these two values to be (numerically) the same we have to set and solve for the radius:
So, one (trivial) solution is . A circle with radius 0 is just a point, and so both area and circumference are zero.
The other solution is . In fact, you have
