Answer:
For any circle of radius r
The diameter of the circle = two times of the radius = 2r
And The Circumference= C = 2πr
14. If r = 8
So, d = 2r = 2 * 8 = 16 cm
C = 2πr = 2 * π * 8 = 50.27 cm (to the nearest hundredth.)
15. If d = 9 m
So, d = 2r
∴ r = d/2 = 9/2 = 4.5 m
And C = 2πr = 2 * π * 4.5 = 28.27 m (to the nearest hundredth.)
The probability of hitting the black circle is closer to 0 than it is to 1. because: find area of circle ~ 3.14*r^2
which is 3.14 because the radius squared is 1. so 1*3.14= 3.14
and the area of the whiteness is 121.
subtract 3.14 from 121 and you get 117.86
this answer is closer to a 0 probability than the white space. the white space is closer to a probability of 1.
