Your first answer is correct.
None of my answers match your choices in the second problem.
Your third answer is wrong.

Pi only means 3 for us. Not any of the other numbers if that helps.

Because I thought the formula for an area of a circle is π(r)^2

OK. If you're using 3 for pi, then your answer is right. Most people use 3.14 for pi.
