Answer:
The sample size is 183.
Step-by-step explanation:
Given:
σ = $1050, ppulatin standard deviation
99% confidence interval
Accuracy = +/- $200
The accuracy is given by
z*(σ/√n)
where
z* = 2.576 for 99% confidence level (from tables)
n = sample size
Therefore
2.576(1050/√n) = 200
√n = (2.576*1050)/200 = 13.524
n = 182.9
<em>The sample size is 183</em>

Step-by-step explanation:
The general formula for the volume of a sphere is:
V = 
The radius for the given sphere is 5mm, so plugging that value into the equation and using 3.14 for π:
V = 
V ≈ 523.33 mm³
