Priscilla is riding a circular rollercoaster, with a diameter of 19 meters. How far does Priscilla travel in one full trip around the rollercoaster?

To find the distance Priscilla travels in one full trip around the circular rollercoaster, we need to calculate the circumference of the circle.

The formula for the circumference \( C \) of a circle is:

\[
C = \pi \times d
\]

where \( d \) is the diameter of the circle. In this case, the diameter \( d \) is 19 meters.

Substituting the value of \( d \):

\[
C = \pi \times 19 \approx 3.1416 \times 19 \approx 59.69 \, \text{meters}
\]

So, Priscilla travels approximately **59.69 meters** in one full trip around the rollercoaster.

### 5 Related Questions:
1. How would the distance change if the diameter of the rollercoaster were doubled?
2. What is the radius of the rollercoaster?
3. How can we calculate the time taken to complete one trip if Priscilla is moving at a constant speed of 10 m/s?
4. What would the distance be for two full trips around the rollercoaster?
5. How would you calculate the distance if the rollercoaster had an elliptical shape instead of circular?

### Tip:
Always double-check whether you're dealing with the radius or the diameter when solving circle-related problems.
