Answer 4

It's ok, do you know the formula for finding the area of a circle?

Answer 5

no

Answer 6

i am not good with circles

Answer 7

Ok, the formula is \[A=\Pi r ^{2}\] That symbol being "pie" do you have any ideas on how to insert the radius to simplify?

Answer 8

maybe this is just a guess 5.6 * 3.14 maybe

Answer 9

Close, you need to first square 5.6, the radius, before multiplying it by pie, 3.14, since in the order of operations, exponents go before multiplying. Try and square 5.6 and see what you get.

Answer 10

so 31.36

Answer 11

Right! Now multiply 31.36 by pie,3.14, to get the answer!

Answer 12

i got 98.4704 so it would be 98.5 sq. inches right

Answer 13

Exactly! So your answer would be D.
