Answer: I think it's 4.9%
Step-by-step explanation:
I got this from another website so bare with me if this is wrong.
"Find the area of the board (this will be your sample space)
and area covered by the bull's eye (this will be numerator for calculating probability)
area of circle = πr^2
for the board, radius = 18
for the bull's eye, radius = 4
4^2π/18^2π
Pi gets canceled out
Multiply what you have left by 100
4^2/18^2 * 100 = 4.938% or 4.94% which can be rounded to the nearest tenth, which is 4.9%
