A sphere with a diameter of 5 feet long is being painted. how much more paint would be needed to paint a sphere that has four ti
MArishka [77]

well, if the diameter is 5, thus its radius must be half that, or 2.5, and therefore, the radius of the one four times as much will be (4)(2.5).

Let's simply get their difference, since that'd be how much more is needed from the smaller to larger sphere.

~\hfill \stackrel{\textit{surface area of a sphere}}{SA=4\pi r^2}\qquad \qquad r=radius~\hfill \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\large difference of their areas}}{\stackrel{\textit{radius of (4)(2.5)}}{4\pi (4)(2.5)^2}~~ - ~~\stackrel{\textit{radius of 2.5}}{4\pi (2.5)^2}}\implies 100\pi -25\pi \implies 75\pi ~~ \approx ~~235.62~ft^2

Answer: p-value \approx 0.01

Step-by-step explanation:

Hypothesis testing

\\\left\{\begin{matrix}H_0 : \mu_0 =0\\ H_1: \mu_0 \neq 0\end{matrix}\right.\\

For this problem, we need to use the t-student distribution to  make inference about the data. We calculate the t-statistics as below:

\bar{X} = 20\:\mu m\\S.E. = 60\:\mu m\\n=82\\t_{stat} = \frac{\bar{X}-\mu_0}{S.E/\sqrt{n}}=\frac{20-0}{60/\sqrt{82}}=3.0185

Using a t-statistics table, or using the function TDIST in Microsoft Excel with t_{stat} = 3.0185,\: df (degree\: of\: freedom) = 14 - 1 = 13 with two-tailed distribution, we obtain p-value \approx 0.01.
