A cylinder has a height of 4 inches greater than the radius of its base. Find the radius and the height to the nearest inch if t
anastassius [24]

Answer:

h=5in, r=1in

Step-by-step explanation:

The volume of a cylinder is:

V=\pi*r^2*h

where r is the radius and h is the height.

The height is 4 inches greater that the radius, so:

h=r+4in

Substituting this in the formula for volume:

V=\pi*r^2*(r+4)

the volume is V=5\pi in^3

thus:

5\pi in^3=\pi*r^2*(r+4in)

Dividing everything between pi:

5in^3=r^2*(r+4in)

5in^3=r^3*+4r^2

We can see that the solution for this is r=1in

since (1)^3*+4(1)^2=1+4=5

We have the radius, now we find the height:

h=r+4in=1in + 4in = 5in

h=5in, r=1in

What does it mean for an equation to have no solution or infinite solutions? How does the equation appear when those are the out
Sati [7]
Ok so  if a system has no solutions, that means that no value will make it true

infinite solutions means that all numbers wil make the system true


example of no solution

a simplification that gives you
3=0
that is false so no solution


example of infinite
if after simplify you get
x=x
you can put all numer for x and get right answer






the simplified form of an equation with no solution will be in the form a=b where a is not equal to b, basically it gives you an obviously false statement like 3=4

simplified form on an equation with infinity solutions would end up with variable=variable or x=x or y=y

Train A arrives at central station on the hour and every 12 minutes. Train B arrives on the hour and every 15 minutes. When do both trains arrive at thesame time? 

I believe that both trains would arrive at the same time on the hour (D).

Hope this helped :)
