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
4,135 divided by 14 is 295.4
The slope =0. Horizontal lines have a slope of 0
Answer:
22.5 miles per hour (rounded answer)
Step-by-step explanation:
This is a fraction equal to
18 miles ÷ 0.8 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 0.8
18 miles ÷ 0.8
0.8 hours ÷ 0.8
=
22.5 miles
1 hour
=
22.5 miles
hour
= 22.5 miles per hour
