Answer
$153.86\ m^2$
Work Step by Step
Use the formula for the circumference of a circle to find the radius of the flowerbed.
$C=2\pi r\longrightarrow$ substitute the given values
$14\pi=2\pi r\longrightarrow$ divide each side by $2\pi$
$7=r$
Use the formula for the area of a circle and substitute the radius to find the area of the flowerbed.
$A=\pi r^2=3.14\times(7^2)=3.14\times49=153.86$
