Answer:

6 inches

Step-by-step explanation:

Formula for surface area of a cylinder:

SA=2\pi r^{2} +2\pi rh

Plug in values and solve for the radius:

180\pi =2\pi r^{2} +2\pi r(9)\\

Divide both sides by 2\pi

90=r^{2} +r(9)

Subtract 90 from both sides

0=r^{2} +9r-90

Use the quadratic equation to find the roots

x=(-b±\sqrt{b^2-4ac})*\frac{1}{2a} (sorry for formatting, Brainly doesn't

                                           allow equations with ± in them)

x=\frac{-9+\sqrt{9^2-4*1*90} }{2(1)}        and          x=\frac{-9-\sqrt{9^2-4*1*90} }{2(1)}

x=\frac{(-9+\sqrt{81+360})}{2}          and          x=\frac{(-9-\sqrt{81+360})}{2}

x=\frac{(-9+\sqrt{441})}{2}               and          x=\frac{(-9-\sqrt{441})}{2}

x=\frac{(-9+21)}{2}                   and          x=\frac{(-9-21)}{2}

x=\frac{12}{2}                           and          x=\frac{-30}{2}

x=6                             and          x=-15  

We can't have a negative radius, so that leaves us with r=6 in.

An automobile manufacturer claims that its van has a 40.3 miles/gallon (MPG) rating. An independent testing firm has been contra
vovikov84 [41]

Answer:

The value of the test statistic is -2.64.

Step-by-step explanation:

The test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected(claimed) mean, \sigma is the standard deviation and n is the size of the sample.

An automobile manufacturer claims that its van has a 40.3 miles/gallon (MPG) rating.

This means that \mu = 40.3

After testing 250 vans, they found a mean MPG of 39.9. Assume the standard deviation is known to be 2.4.

This means, respectively, that:

n = 250, X = 39.9, \sigma = 2.4

So

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{39.9 - 40.3}{\frac{2.4}{\sqrt{250}}}

t = -2.64

The value of the test statistic is -2.64.
