When a research question asks you to find a statistical sample mean (or average), you need to report a margin of error, or MOE, for the sample mean. The general formula for the margin of error for the sample mean is the population standard deviation, n is the sample size, and z* is the appropriate z*<span>-value for your desired level of confidence

</span>1.Find the population standard deviation and the sample size, n<span>.
</span><span>2.Divide the population standard deviation by the square root of the sample size.
</span>3.Multiply by the appropriate z*<span>-value.

Which is closest to the volume<br> of a sphere with a radius equal<br> to 8 centimeters
NemiM [27]

Answer:

The volume of the sphere with radius 8 cm is 2143.573 centimeters³

Step-by-step explanation:

Given as :

The radius of the sphere = r = 8 cm

Let The volume of sphere = v cm³

<u>Now, According to question</u>

Volume of sphere = \dfrac{4}{3} × π × radius³

where r is radius of sphere

π  = 3.14

Or, v =  \dfrac{4}{3} × 3.14 × r³

Or, v =  \dfrac{4}{3} × 3.14 × 8³

Or, v =  \dfrac{4}{3} × 1607.68

Or, v = \dfrac{4\times 1607.68}{3}

∴   v = 2143.573 cm³

So, The volume of the sphere = v = 2143.573 cm³

Hence, The volume of the sphere with radius 8 cm is 2143.573 centimeters³ Answer
