Answer:56.52m, Eugene used a wrong formula
Step-by-step explanation:
diameter=18m
π=3.14
Circumference of circle=π x diameter
Circumference of circle=3.14 x 18
Circumference of circle=56.52m
Eugene used a wrong formula
Circumference of circle=2 x π x diameter
instead of
Circumference of circle=π x diameter
I'll abbreviate
and
, so the identity to prove is

On the left side, we can simplify a bit:


Then

So the establish the original equality, we need to show that

Combine the fractions:

We can rewrite the denominator as

then using the fact that
, we get

so that we have

as desired.
<h2>The distance between two points is

or 9.9 units</h2>
<em><u>Solution:</u></em>
<em><u>The distance between two points is given as:</u></em>

From given,

<em><u>Substituting the values we get,</u></em>

Thus the distance between two points is
or 9.9 units
