Question 1025624
Use the formula of circumference to get the radius of the pond,
{{{C=2pi*R}}}
{{{68pi=2pi*R}}}
{{{R=34}}}{{{ft}}}
So then the path is the region between a circle of radius 38' and a radius of 34'.
{{{A=pi*(R[2]^2-R[1]^2)}}}
{{{A=pi*(38^2-34^2)}}}
{{{A=pi*(1444-1156)}}}
{{{A=288pi}}}{{{ft^2}}}
