A negative number squared equals a positive number. When multiplying, odd numbers of negatives result in a negative answer, and even numbers of negatives result in a positive answer.
When we say "negative 10 squared," we are asking for the result of squaring the number -10. Squaring a number means multiplying it by itself, so (-10) squared is (-10) x (-10), which equals 100. The negative sign is not squared along with the number itself; it simply indicates that the result is negative.

I believe you are supposed to calculate nine squared, and then subtract one from the result.
345 = 345
Since area equals Pi times radius squared take and substitute what is known. 345 equals Pi times the radius squared. divide Pi into both sides for 109.8 equals the radius squared. Now take the square root of 109.8 to get an r of 10.47936 cm.
A negative number squared equals a positive number. When multiplying, odd numbers of negatives result in a negative answer, and even numbers of negatives result in a positive answer.
