Area of a circle = pi x r^2
68.87 cm^2 = pi x r^2

Current scientific undestanding, is that the answer to this question is 1 cord of wood per day per woodchuck.
You have to do the multiplication first, so it looks like this
3 - (3x6) + 2
3 - 18 +2
then you can do the operations in any order
3-18+2= -13
It may be a decimal if it isn't a multiple of complete wavelengths. DO you want to convert the decimal into a fraction?

There are MORE than 4 sig digs in your number, but if you only want 4:

The FRACTION of goats is tripled..not the NUMBER (as I calculated earlier)
x/240 = original fraction
ADD 40 goats to TRIPLE the fraction
(x+40)/280 = 3(x/240)
x+40 = 840x/240
40 = 840x/240 - x
x=16 (original number)
x+40 =56 New number of goats
40 + x = 3x
40 = 2x
x = 20 goats originally
60 goats now
