Answer:

Step-by-step explanation:
The formula for the circumference of a circle with the diameter is:

Since the diameter is 3m, solve for
:

Answer:
milligram would be 3.2e+7 or if not 3.2
#6 is 48 degrees and #7 is acute
-6 because for every value (x,y) there is another value (-x,y) so for the value (6,0) there must also be a value (-6,0). That is what the definition of y-axis symmetry is, it is also known as being an "even" function if it has this type of symmetry. Look at the graph of y=(x^2)-36 to see how this works.
The answer for the equation is (4, -2)
