A best estimate is the best guess that you can give for an answer. It is not really done using a formula, just by comparing things in your mind.
The best estimate is, of course, the correct value, which is so easy to calculate that I am astounded that anyone would want to estimate it. 128 + 375 = 125 + 3 + 375 = 125 + 375 + 3 = 500 + 3 = 503 The second best is 500.
guess or estimate
You have to calculate the radius - half the diameter. Then square the radius, and multiply by pi (approximately 3.1416). If you want to do a mental estimate, round pi to 3.

It is 60 as the best estimate for 57
The BEST estimate can only be 2852.831 anything else is not BEST.
what is the best estimate of the capacity of a soda can
too great to calculate or unable to estimate
You can calculate 3444 times 670 without rounding or you can estimate it WITH rounding. But you cannot estimate it without rounding.
I don't think there is any easy way to estimate it; just use the quadratic equation to calculate the solutions. You can round some of the numbers to get an estimate; in this case you might even do most of the calculation in your head, but it's probably easier just to do the full calculation.
