What is the height of a cylinder with a radius of 3 and a volume of 189?

Answers

Answer:

6.68 units (2 d.p.)

Step-by-step explanation:

The formula for the volume of a cylinder is:

[tex]\boxed{V=\pi r^2 h}[/tex]

where:

V is the volume.r is the radius of the circular base.h is the height.

Given values:

V = 189 cubic unitsr = 3 units

To find the height of the cylinder, substitute the given values into the formula and solve for h:

[tex]\implies 189=\pi \cdot 3^2 \cdot h[/tex]

[tex]\implies 189=9\pi \cdot h[/tex]

[tex]\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}[/tex]

[tex]\implies \dfrac{189}{9 \pi}=h[/tex]

[tex]\implies h=6.6845076...[/tex]

Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

Answer:

h≈6.68

Step-by-step explanation:

6.68 is the height of a cylinder with a radius of 3 and a volume of 189

Answer:

560 ft squared

Step-by-step explanation:

Square side: 10 x 10 = 100

Rectangle Side: 14 x 10 = 140

2 (100 + 140) = 480 ft squared is the base

Triangle Roof: 9 x 14 = 126

126 x 2 = 152

Front and back of triangle: 10 x 8 = 80 ft squared

Answer 480 + 80 = 560 ft squared

You would have to divide by 2 if there was 1 front triangle and no back because a triangle is half of a square and you multiply how a square does and divide by 2.

Step-by-step explanation: volume of a rectangular prism is L×W×H

therefore 82.8=L×W×the height which is 4 units so if u do 4×L×W you get 4LW which is the volume

(4LW=82.8) now divide 82.8 by 4LW to get the value of LW. The value of LW is an area of one of the bases because area is L×W which is basically LW

johnny had to work in the morning and 8 hour shift. he clocked in at 8:00am to began working and then clocked back out for 30 min lunch break at 11:06am -11:36 am. he clocked back out at 11:43 am because he got sick. now he has return back to wirk and clocked in at 3:21pm what time will johnny gets off in order to make his 8 hours?

Answers

Answer:

8:08pm.

Step-by-step explanation:

So he worked 3 hours 6 minutes from 8am-11:06am.

Then he worked another 7 minutes from 11:36-11:43am. That brings our running total to 3 hrs 13 minutes.

To work 8 hours, he needs to work 8 hrs - 3 hrs 13 minutes = 4 hrs 47 minutes more.

He's starting a 3:21pm.

First add on the 4 hours. 3:21pm + 4 hours = 7:21pm.

Now add on 47 more minutes. If we add 39 minutes, that brings us to 8pm. He would have 47-39=8 more minutes to work. That brings us to 8:08pm.

The answer is 8:08pm.

Find the value of c that will make the following two expressions equivalent to 4!!

The answer is 4, Our teacher gave us the answer but I need the work to show how she got it.

2a+10b-8-2(4a-6) and -6a+10b+c

Answers

Answer:

see below

Step-by-step explanation:

We are given 2 equations:

[tex]2a+10b-8-2(4a-6)\\-6a+10b+c[/tex]

We are told to find c to make them equivalent, so we can make them equal to each other:

2a+10b-8-2(4a-6)=-6a+10b+c

To find c, we have to isolate it, here are the steps:

2a+10b-8-2(4a-6)=-6a+10b+c

subtract 10b from both sides

2a-8-2(4a-6)=-6a+c

rearrange left side

2a-2(4a-6)-8=-6a+c

distribute the positive 2 to the terms in parenthesis

2a-(8a-12)-8=-6a+c

distribute -1 to the terms in parenthesis

2a-8a+12-8=-6a+c

simplify

-6a+4=-6a+c

add -6a to both sides

4=c

Hope this helps! :)

Answers

Answer:

1. slope = 12

  y-intercept = 1/3

2.slope = 1/4

  y-intercept= -12

3.slope = 3

  y-intercept = 2

Step-by-step explanation:

When you get an equation for a graph, the co-efficient infront of the x (The number by the x) is the slope.

The equation for the y-intercept:

When solving for y-intercept, you replace y in the equation with 0 and make x the subject.

Example:
y = 12x - 4

0=12x - 4

-12x = -4

divide both sides by negative 12 since we want only positive x

[tex]\frac{-12x}{-12} =\frac{-4}{-12}[/tex]

x = [tex]\frac{1}{3}[/tex]

Therefore, the y-intercept = 1/3

Find the value of c that will make the following two expressions equivalent.

2a+10b-8-2(4a-6) and -6a+20b+c

Answers

We can begin by simplifying the first expression:

2a+10b-8-2(4a-6) = 2a+10b-8-8a+12
= -6a+10b+12

Now we need to find the value of c that makes -6a+10b+12 and -6a+20b+c equivalent. In order for them to be equivalent, they must have the same coefficients for a and b. The coefficient for a is already the same (-6), so we just need to make the coefficient for b the same:

10b = 20b
10b - 20b = 0
-10b = 0
b = 0

Now that we have found the value of b, we can substitute it back into either expression to find the value of c:

-6a+10b+12 = -6a+10(0)+12
= -6a+12

-6a+20b+c = -6a+20(0)+c
= -6a+c

Since these expressions are equivalent, their coefficients for a must also be equal:

-6a+12 = -6a+c

Simplifying this equation, we find:

12 = c

Therefore, the value of c that makes the two expressions equivalent is 12.
