Leno4ka [110]

Answer:

It's $32.39.

What is the best approximation for the area of a circle with a diameter of 13 meters?
Illusion [34]
First, find the radius of the circle. The radius of a circle is half the diameter. r=13/2=6.5 

Second, use the equation A=pi * r^2 to find the area of the circle. 
A=(3.14) * (6.5^2) = 132.665m^2 

so the answer is 132.7 m^2.
