Area of square = 16 x 16 = 256 ft²
Area of circle = r²
radius = 16 ÷ 2 = 8

Shaded area = 256 - 200.96 = 55.04 ft²
Answer: Minimum sample size = 110
Step-by-step explanation:
Formula to find minimum sample size :
, where z = critical z-value for confidence level, s= sample standard deviation , E = margin of error
Given: E= 4 , s= 18
Critical z-value for 98% confidence = 2.327
So,
Minimum sample size = 110
