What is the height of the cone below? ​

Mathematics

Paul [167]3 years ago

The height of the cone is h = 27

Formula:-

Step 1:-

The volume of the cone is  V=\frac{1}{3} (base)(height)V=31(base)(height)

Given volume is V= 45 in^ 3

Given base of the cone is B= 5 in^2

Step 2:-

by using formula, we get solution

45 = \frac{1}{3} (5)(h)45=31(5)(h)

cross multiplication, we get

\frac{45 x 3}{5} =h545x3=h

<em>now simplification, the height of the cone is h = 27</em>

Answer:

27 in.

Step-by-step explanation:

Firstly, let's look at what we do know. We need to find the height of a cone and we know the area of the base (B) and we know the volume of the cone.

The first step is to determine the radius of the base, which we can use later.

The area of a circle is A = π r^2, so when we plug in the given information

5 = π r^2

And now we can solve for the radius

5/π = r^2

√(5/π) = r

r = 1.26

Now that we have the radius of the base, we can find the height of the cone using the volume formula.

V = π r^2 (h/3)

45 = π (1.26)^2 (h/3)

45 = π (1.59) (h/3)

45/(1.59π) = h/3

9.01 = h/3

3(9.01) = h

h = 27 in

Please help STRUGGLING with math few math questions! Ty
-BARSIC- [3]

Question 1:


F(x) and g(x) are like variables, just plug into the equation.


f(x) + g(x) = (x + 6) + (12x - 7)


x+6+12x-7 = 13x-1


Question 2: f(3) + g(-1)


You plug in the x-values into the equation, and then take the answer and add them together.


f(3) = 3+4

g(-1) = 12(-1)-6


f(3) = 7

g(-1) = -18


7 + (-18) = -11


Question 3:


This is similar to question 1, plug in the variables and simplify.


9x - (7x+3)


Remember to distribute the "-"


9x - 7x - 3

2x - 3

A researcher asks random samples of residents of two separate counties as to whether they had purchased organically grown food i
Leni [432]

Answer:

2 proportions z test

The two populations are named as residents from the first county and residents from the second county.

Step-by-step explanation:

This is testing hypothesis about the difference between two proportions.

When the proportions are tested if they are the test statistic

z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂

where p^1 is the proportion of success in the first sample and   p^2 of size n₁   is the proportion of success in the second sample of size n₂ with unknown proportions of successes p1 and p2 respectively.

When the sample sizes are sufficiently large

z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂ is approximately standard normal.

The two populations are named as residents from the first county and residents from the second county.
