Answer:



And that's different from the claim of the student that:

The error of the student is that he/she changes the sign of the inequality from
to
and that's not possible since we don't multiply both sides of the equation by -1
Step-by-step explanation:
For this case we have the following inequality:

We want to rewrite the last expression with y in the left and x in the right so we can begin adding 3 in both sides of the inequality and we got:

Now we can divide both sides of the inequality by 2 and we got:

And that's different from the claim of the student that:

The error of the student is that he/she changes the sign of the inequality from
to
and that's not possible since we don't multiply both sides of the equation by -1
Answer:
207°
Step-by-step explanation:
Area =

so if the diameter is 16, radius (r) = 8
3.14 * 8^2 = 3.14*64 = 200.96 is the approximate area
If you're looking for the answer in terms of pi, 64pi is the answer.
