Answer 1

To find the distance Caleb skated in one lap along the edge of the circular rink, we need to calculate the circumference of the circle.

The formula for the circumference \( C \) of a circle is given by:
\[
C = \pi \times d
\]
where \( d \) is the diameter of the circle.

In this case, the diameter of the rink is 99 feet. Plugging that into the formula, we get:

\[
C = \pi \times 99
\]

Thus, the distance Caleb skated in one lap is:
\[
99\pi \text{ feet}
\]

So, the final answer is:
\[
99\pi \text{ feet}
\]
