Question

done

Answer 1

You first calculate the area of square, than substract 4 times the area of that quarter a circle

Answer 2

4 times the area of a 1/4 of a circle ... is the area of a full circle :)

Answer 3

what's the area of the square?

Answer 4

that's the area of a full circle with radius 14

what is the area of one-quarter of that full circle?

Answer 5

take the full area and divide it by 4 (leave it in terms of pi)

Answer 6

actually because there are 4 congruent circular pieces in each corner, you can combine those pieces (each 49pi square inches each) to get 196pi square inches

Answer 7

now what is the area of the square?

Answer 8

what was done so far was figuring out the area of the circle pieces

Answer 9

that's not the area of the square

Answer 10

yes

Answer 11

what's the side length of the square

Answer 12

14 is NOT the side length of the full square

and you're using the perimeter formula

Answer 13

14 is half the side length

so the full side length is ???

Answer 14

good, now subtract off 196pi

Answer 15

so your final answer is

\[\large 784 - 196\pi\]

Answer 16

no you just leave it like that

Answer 17

you cannot combine 784 and 196pi

Answer 18

you just leave it like \[\large 784 - 196\pi\]
