If two cylinders have the same radius, but one has a height two times larger

Mathematics
1 answer:
sweet [91]3 years ago
5 0

The volume of the large cylinder will be twice the volume of the small cylinder.

<u>Step-by-step explanation:</u>

Let the radius of the cylinder be 'r'

Let the height of the cylinder be'h'

Volume of the small cylinder=π r² h

Volume of the large cylinder= π r² (2h)

Volume of large cylinder/volume of small cylinder= 2/1

The large cylinder volume is twice the volume of the small cylinder.

What is an equation of the line that passes through the point (−3,−1) and is perpendicular to the line x-2y=6?
gogolik [260]

Answer:

y = 2x+5

Step-by-step explanation:

rearrange the equation to make y the sof

y = 1/2x - 3

to find gradient of perpendicular line

1/2 ÷ ( - 1 )

y = -2x + c , the replace the coordinates (-3,-1)

y = 2x + 5

WZ and XR are diameters of circle C. The diagram is not drawn to scale. What is the measure of ZWX?
Inessa05 [86]

Answer:

Measure of arc ZWX is <u>230°.</u>

Step-by-step explanation:

Given:

arc WX = 50°

Now

The diameter divide a circle into two equal parts

so

arc\ ZWX=arc\ ZRW+arc\ WX

Since WZ is diameter of the circle.

arc\ ZRW=180\°

substituting in above equation we get

arc\ ZWX=180\°+50\°=230\°

Hence Measure of arc ZWX is <u>230°.</u>

A 100-meter-long christmas train needs 30 seconds to cross a 400-meter-long bridge. assuming the train goes at a steady speed, h
san4es73 [151]
Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30

speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===

a fragpole is 10 feet tall. It’s shadow is 12 feet long. How far is it from the lip of the fragpole to the end of its shadow?
Masteriza [31]
Standing beside the flagpole(if that's what you meant), shadow is two feet longer so you would have two feet more than needed

Solveby factoring : <br> p2 + 8p + 12 = 0<br> (show steps please)
kramer

Answer:

(p + 6)(p + 2)

Step-by-step explanation:

I believe you meant  p^2 + 8p + 12 = 0, in which " ^ " indicates exponentiation.

Note that 12 = 2*6, and that these two factors, 2 and 6, add up to 8.  Thus,

p^2 + 8p + 12 = 0 = (p + 6)(p + 2)
