How do I find lateral height with only surface area and length of the edge?

1 answer:

7 0

I'm guessing you are talking about the surface area of a cone?
Also by length of the edge, do you mean slant height?
Here is the area formula for a cone:
Lateral Area = (π • r • slant height)
Solving for "r" we get:

radius = Lateral Area / (π • slant height)

When you calculate the radius, you can solve for the height by
height^2 = slant height^2 - radius^2

Y_Kistochka [10]

Answer:

6682

Step-by-step explanation:

So we have a 4 digit number and we need to find all the digits of it.

First, we are told that the one digit is 2. So the number is xxx2

Now, we know that the tens digit is 4 times greater than the ones, thus, the tens digits is 4 times 2, this is 4(2) = 8. Thus, the tens digit is 8 and the number is xx82.

Finally we know that the hundreds and thousands are both 3 times greater than the ones, so the digits are 3(2) = 6. Thus the hundreds and thousands are 6 and the final number is 6682.
