Answer:
5
Step-by-step explanation:
4(x+3) is 4x+12
2x+22=4x+12
-2x from both sides
get 22=2x+12
-12 from both sides
get 10=2x
divide by 2 to both sides
get 5
I'm guessing you are talking about the surface area of a cone?
<span>Also by length of the edge, do you mean slant height?
Here is the area formula for a cone:
Lateral Area = (<span>π<span> • r •<span> slant height)
Solving for "r" we get:
</span></span></span></span>
radius = Lateral Area / (<span>π<span> • </span></span><span><span>slant height)</span><span><span /></span></span>
When you calculate the radius, you can solve for the height by
height^2 = slant height^2 - radius^2
