Set up an equation and solve the following problem.
Find the length of a radius of a circle such that the circumference of the
circle is numerically equal to the area of the circle.
:
We know, Area = and Circumference =
Problem is: Area = Circumference, therefore
=
Divide both sides by
=
Cancels the , we are left with
:
r = 2 is the length of the radius
;
:
See if that is true
= 12.556
= 12.566; of course r=2 is the only value where this is true, right?
