Answer:
A=πr²=π·3²≈28.27433
To find the area of a circle, use the equation πr²
The image is a bit blurry so from what I saw r (radius) is 3 otherwise you can use this equation if r is not 3.
If π was replaced with 3.14 the answer is 28.26 ft².

The correct option is D
Step-by-step explanation:
From the question we are told that
The sample size is 
The number that developed nausea is X = 50
The population proportion is p = 0.20
The null hypothesis is 
The alternative hypothesis is 
Generally the sample proportion is mathematically represented as


Generally the test statistics is mathematically represented as
=> 
=> 
=> 
The p-value obtained from the z-table is

Given that the
then we fail to reject the null hypothesis
492.3069 rounded to the nearest thousandth is 492.307 :-)
