ANSWER
V=254.47in^3

EXPLANATION

The volume of a cylinder is given by the formula:

V=\pi \: {r}^{2} h

The given cylinder has diameter 6. This means that, the radius is

r = \frac{6}{2}

r = 3cm

The is height is

h = 3r

h = 3(3) = 9cm

We substitute the values into the formula to obtain;

V=\pi \: {3}^{2} \times 9

V=81\pi

V=254.46900494

The volume is 254.47in^3 to the nearest hundredth

Answer:

V  = 254.47 inches³

Step-by-step explanation:

We have given the diameter of cylinder and relation of height and radius of cylinder.

Let d ,r and h denotes the diameter,radius and height of the cylinder respectively.

d  = 6 inches and h = 3r

We have to find the volume of the cylinder.

V  = ?

The formula to find volume of cylinder is:

V  = πr²h

The formula to find radius while diameter is given:

r  = d / 2

r  = 6 / 2  = 3 inches

h  =  3r

h  = 3(3)  = 9 inches

Putting above values in formula , we have

V  = π(3)²(9)

V  = 81 π

V  = 254.47 inches³ which is the answer.

Sunny_sXe [5.5K]

Answer:

See explanation

Step-by-step explanation:

Dinosaur Discovery show = 8 friends

Wild Weather show = 4 friends

Cost of Dinosaur Discovery show = $d

Cost of Wild Weather show = $w

At regular price:

Total cost of his friends' tickets = 8 * d + 4 * w

= 8d + 4w

At half price

Total cost of his friends' tickets =

8 * 1/2d + 4 * 1/2w

= 8/2d + 4/2w

= 4d + 2w

Total cost of his friends' tickets = 4d + 2w

BaLLatris [955]

Answer:

The test statistic is z = 1.25

Step-by-step explanation:

We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.

At the null hypothesis, we test if the proportion is 80%, that is:

H_0: p = 0.8

At the alternate hypothesis, we test if the proportion is more than 80%, that is:

H_a: p > 0.8

The test statistic is:

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

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

80% is tested at the null hypothesis:

This means that \mu = 0.8, \sigma = \sqrt{0.2*0.8} = 0.4

A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.

This means that n = 100, X = \frac{85}{100} = 0.85

The test statistic is

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

z = \frac{0.85 - 0.8}{\frac{0.4}{\sqrt{10}}}

z = 1.25

The test statistic is z = 1.25

Pat shows that 16 1/2= the square root of 16. What is one possible way pat could have shown this correctly?
kifflom [539]
<h3>Answer: Choice C</h3>

The base 16 is the same as 4*4.

From there, the rule (a*b)^c = a^c*b^c is used to get (4*4)^{1/2} = 4^{1/2}*4^{1/2}

Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is a^b*a^c = a^{b+c} which only works if the bases are both the same.
