Answer:

h=S/(2\pi r)

Step-by-step explanation:

we know that

The surface lateral area of a cylinder is equal to

S=2\pi rh

where

r is the radius of the base of the cylinder

h is the height of the cylinder

Solve for h-------> means isolate the variable h

so

Divide by 2\pi r both sides

S/(2\pi r)=2\pi rh/(2\pi r)

Simplify

h=S/(2\pi r)

First you want to get h alone so you divide 2<span>π</span>r by s so your answer would be
h=S/2πr

What percent of 60 is 15?
kvasek [131]
Well the first one you have to divide both sides by 60 to get x. 
=60x/60=1500/60 
x=25
your answer is 25%

second one...think of it as 18/50. multiply by 2 and you get 36/100

Three locations are marked next to a river. Points B and C are on the same side of the river, and point A is on the other side o
nlexa [21]

Answer:

74.31353

=74 m

Step-by-step explanation:

given that three  locations are marked next to a river. Points B and C are on the same side of the river, and point A is on the other side of the river. To find the distance AB across a river, a distance BC of 241 meters is laid off on one side of the river. It is found that the angle at point B is 108.6° and the angle at point C is 14.9°.

we have information about triangle ABC as side BC =241, Angle B = 108.6 and angle C = 14.9 degrees.

Hence this is an obtuse scalene triangle.

Angle ∠A = 56.5° (III angle)

Using sine formula we get

\frac{AB}{sin 14.6} =\frac{BC}{sin 56.5} \\AB = 74.31353

So distance AB is 74 metres.

A rectangular flying carpet is 1 1/2 m wide and 2 m long what is the area of the carpet
d1i1m1o1n [39]

Hi there! :)

<u>Answer:</u>

The area of the carpet is <u>3m²</u>.


Step-by-step explanation:

First off, the formula to calculate the area of a rectangle is this: A = L × W

Where "A" is the area, "L" the length and "W" the width.

Now that you have that, replace all the information you know in the equation in order to find the value of "A", which is what we are looking for:

- Just keep in mind that 1 1/2 is the same thing as 1.5

- The term "wide" is used to give the "width"

- The term "long" is used to give the "length"


A = L × W

A = 2 × 1.5

<u>A = 3</u>


There you go! I really hope this helped, if there's anything just let me know! :)
