Answer 4

plz help me, do u agree with my answer?? or is it wrong, if so , plz explain why

Answer 5

first find the area of the square

Answer 6

area of square =\(side^2=28^2\)

Answer 7

okay

Answer 8

it would be 28 by 28 would it

Answer 9

replace the side with 28

Answer 10

it would be \(28\times 28\)

Answer 11

that would be 784

Answer 12

now what? i am a bit confused.....

Answer 13

ok correct ,

now find the area of circle as the circle is inscribed in the square ,the radius of circle would be \(r=\dfrac{28}{2}\)

Answer 14

14

Answer 15

area of circle =\(\large \pi r^2\)

Answer 16

the closest is a

Answer 17

615.75

Answer 18

Now find the area of the circle inside the square, and subtract the area of the circle from the area of the square.

Answer 19

area of circle =\(3.14\times 14\times 14\)

Answer 20

615.44

Answer 21

If you use \(\pi = 3.14\), then one of the choices has the exact answer.

Answer 22

ok correct now

find the difference of

area of square -area of circle

Answer 23

okay, so 28 divided by 2 is 14, and 14 times pi is 43.96 right?

Answer 24

659.40

Answer 25

the above statement is same as \(\large 784-615.44\)

Answer 26

right @mathmath333 and @mathstudent55

Answer 27

so a basically

Answer 28

i am going with a, thx
