Question

Find the ratio of the area outside the circle to the area of the square

Answer 1

What is the side of the square?

Answer 2

2r

Answer 3

so the area of the inside of the square but outside the circle is \[4r^2-\pi r^2\] ?

Answer 4

\((2r)^2 - \pi r^2 = 4r^2 - \pi r^2\)

Answer 5

Correct.

Answer 6

\(= r^2(4 - \pi)\)

Answer 7

Now find the ratio by dividing by the area of the square.

Answer 8

\[\frac{ r^2(4-\pi) }{ 4r^2 }\]
\[\frac{ 4-\pi }{ 4 }\]

Answer 9

.215:1 ?

Answer 10

I'd leave it in the exact form as the fraction.

Answer 11

Okay, thanks!!

Answer 12

Good job!
You're welcome.

Answer 13

\(\dfrac{4 - \pi}{4} : 1\)

Answer 14

Okay thx :)
