Sovle for h: v=1/3πr²h

Mathematics
1 answer:
erastovalidia [21]3 years ago
8 0

Answer:

<h2>h = \frac{3v}{\pi {r}^{2} }</h2>

Step-by-step explanation:

v =  \frac{1}{3} \pi {r}^{2} h

To solve for h multiply through by 3 to eliminate the fraction

That's

3v = \pi {r}^{2} h

Divide both sides by πr² to make h stand alone

\frac{\pi {r}^{2} h}{\pi {r}^{2} }  =  \frac{3v}{\pi {r}^{2} }

We have the final answer as

h = \frac{3v}{\pi {r}^{2} }

Hope this helps you

A cone has a height of 8 yards and a radius of 3 yards. What is its volume?
alina1380 [7]
<h3>Given:</h3>
  • h= 8 yd
  • r= 3 yd
<h3>Note that:</h3>
  • h= Height
  • r= Radius
<h3>To find:</h3>

The volume of the given cone.

<h3>Solution:</h3>

\large\boxed{Formula:V= \frac{1}{3}\pi{r}^{2}h}

\large\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}

Let's solve!

Substitute the values according to the formula.

V= \frac{1}{3}×3.14×{3}^{2}×8

\large\boxed{V= 75.36 \: {yd}^{3}}

<u>Therefore, the volume of the given cone is 75.36 cubic yards.</u>

What is the rule of the reflection?
iogann1982 [59]

The rule of reflection in the image shown is: (x, -y).

<h3>What is Reflection?</h3>

Reflection is a transformation which creates a new image by flipping over a line of reflection. The new image is congruent to the original image after reflection. The rule of reflection over an x-axis is given as, (x, -y).

In the image given we can see that rotating triangle LMN over the x-axis gave us:

M(-5, 4) → M'(-5, -4)

L(-4, 2) → L'(-4, -2)

N(-2, 3) → N'(-2, -3)

Therefore, the rule of reflection is: (x, -y).

Rather than use the two scoops of coffee recommended by the manufacturer, a coffee aficionado uses three scoops of coffee per po
Aleks [24]

Answer: Relative error = 50%

Step-by-step explanation:

Relative error Re = Absolute error/True value × 100%

True value = 2 scoops

Measured(used) value = 3 scoops

Absolute error Ae = measured(used) value - True value

= 3 scoops - 2 scoops

Ae = 1 scoop

Re = 1/2 × 100%

Re = 50%
