To calculate the area of a circular play mat, you can use the formula for the area of a circle:
\[ \text{Area} = \pi r^2 \]
Where \( r \) is the radius of the circle and \( \pi \) is approximately 3.14.
However, you haven't provided the radius (or diameter) of the play mat. Please provide that information, and I can help you calculate the area rounded to the nearest hundredth.
