What is the radius of a circle that has the same numerical value for area and circumference? how do the units compare?

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

b mark me branliest thx

step-by-step explanation:

the answer to your question is b.
