It is just asking how many meters tall are doors usually at. Clearly 30 meters isn't reasonable so just say how tall most doors are in meters.

If the cylinder above is similar to a second cylinder that has a radius of 10mm, what is the height of the second cylinder

julsineya [31]

Answer:

The height of the second cylinder is 30mm

Step-by-step explanation:

Given

Cylinder 1:

$R = 15mm$

$H = 45mm$

Cylinder 2

$r = 10mm$

See attachment

Required

Determine h, the height of the small one

To do this, we make use of the following equivalent ratios;

$R : H = r : h$

This gives:

$15 : 45 = 10 : h$

Express as fraction

$\frac{15 }{ 45 }= \frac{10 }{ h}$

Simplify

$\frac{1 }{ 3}= \frac{10 }{ h}$

Cross multiply

$h *1 = 3 * 10$

$h = 30$

Find the circumference of the circle with 1/4 Pi square centimetre square 2<br>

otez555 [7]

Answer:

The circumference of the circle is 6 cm (approximately).

Step-by-step explanation:

Given:

Area of the circle = 1/4π²

Now, to get the circumference of the circle we need the radius.

So, finding the radius by putting the formula of area:

Area = $\pi r^{2}$

$\frac{1}{4} \pi ^{2}$ = $\pi r^{2}$

dividing π by both sides:

$\frac{1}{4}\pi$ $=r^{2}$

using square root on both the sides:

$\frac{1}{2}\sqrt{\pi } = r$

So, the radius is $\frac{1}{2}\sqrt{\pi }$

Now, putting the formula of circumference:

$circumference=2\pi r$

= $2\pi\frac{1}{2} \sqrt{\pi}$

= $\pi \sqrt{\pi}$

putting the value of π =3.14

= $3.14\times\sqrt{3.14}$

= $3.14\times1.77$

= $5.56$

Circumference = 5.56 cm

Therefore, the circumference of the circle is 6 cm (approximately).

Give a example of two fractions with the quotient of 5/12

olasank [31]

Poorly phrased question, but the general answer is 5k/(12k), where k <span>∈ Z (i.e. k is an integer).

So, 5/12 and 10/24.</span>
