Answer:

r = (3V/π)^1/3

Step-by-step explanation:

Given that :

Volume of a sphere = V = 4/3πr³

Dividing into 4

4/3 * 1/4 πr³ = 4/12πr³ = 1/3πr³

V = 1/3πr³

Cross multiply

3V = πr³

Divide both sides by π

3V/ π = πr³/ π

3V/ π = r³

Take the cube root of both sides

r = (3V/π)^1/3

Answer: 2401

Step-by-step explanation:

We know that if prior proportion of population doesn't exist , then the formula to find the population proportion is given by :_

$n=0.25(\dfrac{z_{\alpha/2}}{E})^2$

Given : Level of confidence = 0.95

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Margin of error : $E=0.02$

Then ,we have

$\Rightarrow n=0.25(\dfrac{1.96}{0.02})^2=2401$

Hence, the minimum sample size needed =2401
