Surface area and volume of cone

faust18 [17]

The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.

<h3>What is volume?</h3>

Volume is the capacity of an object.

To calculate the surface area and volume of the cone shown above, we use equation 1 and equation 2 respectively.

Formula:

S = πr√(r²+h²)............. Equation 1
V = πr²h.................. Equation 2

Where:

S = Surface area of the cone
V = Volume of the cone
r = Radius of the base of thye cone
h = Vertical height of the cone.

From the diagram,

Given:

r = 10 km
h = 24 km
π = 3.14

Substitute these values into equation 1 and equation 2 respectively.

S = 3.14×10[√(24²+10²)
S = 31.4(√676)
S = 31.4×26
S = 816.4 km²

Also for the volume of tyhe cone

V = 3.14×10²×24
V = 7536 km³

Hence, The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900

rosijanka [135]

Answer:

The 33 week gestation period baby has a zscore of -0.47.

The 41 week gestation period baby has a zscore of -0.94.

The 41 week gestation period baby weighs less relative to the gestation period.

Step-by-step explanation:

Normal model problems can be solved by the zscore formula.

On a normaly distributed set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a value X is given by:

$Z = \frac{X - \mu}{\sigma}$

The zscore represents how many standard deviations the value of X is above or below the mean $\mu$ . This means that the baby with the lowest Zscore is the one who weighs relatively less to the gestation period.

33 week gestation period baby:

Babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900 grams, so $\mu = 2700, \sigma = 900$ .

A 33-week gestation period baby weighs 2275 grams. So $X = 2275$ .

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{2275 - 2700}{900}$

$Z = -0.47$

41 week gestation period baby:

Babies born after a gestation period of 40 weeks have a mean weight of 3200 grams and a standard deviation of 450 grams, so $\mu = 3200, \sigma = 450$

A 41-week gestation period baby weighs 2775 grams, so $X = 2775$ .

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{2775 - 3200}{450}$

$Z = -0.94$

The 41 week gestation period baby weighs less relative to the gestation period, since he has a lower zscore.

Fill in the blanks so the left side is a perfect square trinomial. That is, complete the square.

wlad13 [49]

Focus on 12x. Divide the 12 by 2. = 6.

The answer is (x+6)^2. On the right side

On the left side. Use the 6 and square it. 6^2 =36

Answer::: x^2 + 12x + 36 = (x+6)^2
