Answer 1

Answer 2

We just need to divide the area of the circle by the area of a square, so what is the area of a square and circle?

Answer 3

4?

Answer 4

No..I mean what's the formula

Answer 5

how do i find the formula?

Answer 6

Area of a square is side * side right? So we can say \[A_{\square} = a^2\] and area of a circle is \[A_{circle} = \pi r^2\]

Answer 7

im confused, i dont know what the formula is

Answer 8

Answer 9

Geny, I provided you the formulas, you learn this in elementary. You just remember them for now, now since the radius is half the size of the side of a square we will let 2r be the side of the square, so we have a = 2r putting it all together we have \[A_{\square} = (2r)^2~~~~A_{circle}=\pi r ^2\]

Answer 10

ok then what

Answer 11

So we have \[\frac{ \pi r ^2 }{ (2r)^2 }\]

Answer 12

ok

Answer 13

So plug in the values and evaluate.

Answer 14

can you help me with that though please

Answer 15

i think its A

Answer 16

the area of square is 64, right? @Astrophysics

Answer 17

Yes.

Answer 18

ok so then 4 x 2/8 x 2?

Answer 19

Answer 20

@geny55 have you found the area that is in the square but not in the circle?

Answer 21

hint: to find that area you will need to find the difference between the square's area and the circle's area

Answer 22

notice the square's side length is given by (4+4)
and the circle's radius is given by 4
it should be pretty easy to find the areas of both the square and circle now

and you want to know the difference of these areas over the squares area
