So for your question,
/
There was a 14.4% decrease within 50 years.

Answer:
Step-by-step explanation:
The equation for the area of a circle is A=
.
A=area
r=radius
We were given the diameter of the circle not the radius, so we need to solve for the radius.
Radius=(1/2)Diameter So,
(1/2)6=3mm
Now we can solve for the area.
3^2(3.1415926)=28.2743mm
Now round to two decimal places.
28.27mm
