Question

I have 14 but need the answer to 18. ​

Answer 1

Answer:

18.85 mm.

7.73 mm^2.

Step-by-step explanation:

The side of the square =  sqrt 36 = 6 mm.

Now this side = the diameter of the circle.

So the circumference of the circle = π  * 6 =  18.85 mm.

The answer to the second part

= area of the square - area of the circle

= 36 -  π *3^2

= 36 - 28.27

= 7.73 mm^2.
