===========
Area = pi*r^2
------
Circumference = 2*pi*r

Hi there,
Area of a circle = π x radius^2
√64 = 8
So radius of this swimming pool
= 8 meters.
Circumference (Distance round the
outside of a circle)
= π x 2 x radius
= π x 2 x 8
= 16π
= 50.27 meters (2 decimal places)
The length of the fence.
Hope this helps :-)
