Write a function that takes as its parameters *one or more numbers which are the diameters of circles.* 
The function should return the *total area of all the circles*, rounded to the nearest integer in a string that says "We have this much circle: xyz". 
You don't know how many circles you will be given, but you can assume it will be at least one.
So: 
```python
sum_circles(2) == "We have this much circle: 3"
sum_circles(2, 3, 4) == "We have this much circle: 23"
```
