Question

Geometric probability
PLEASE HELP!

Answer 1

Explanation:

The red sections are sectors of the circle. We need that area. We'll find one then multiply it by 2, since they're both the same.

`A_s=(60)/(360)\pi (4)^2\\A_s=(1)/(6)\pi (16)\\A_s=8.377`and now we multiply it by 2 to get the red area:

`A_s=16.754`

And now the area of the circle:

`A_c=\pi (4)^2\\A_c=16\pi\\A_c=50.265` and now divide to get the percentage:

`(16.754)/(50.265)*100=` 33.3%
