a dart hits the dartboard shown find the probability that it lands in the shaded regions? I don't know how to do this help

Answer:
Step-by-step explanation:
The probability of hitting the shaded area is the shaded area divided by the total area
If the square is 4m then the radius of the circles is 1m
shaded area equals total area minus the area of the circles
S=16-4pi shaded area
T=16 total area so probability of hitting shaded area is
P(S)=(16-4pi)/16
P(S)=(4-pi)/4 (exactly)
P(S)=0.2146 (approximately)
