Final answer:
Susanna travels approximately 59.66 meters in one full trip around the rollercoaster.
Step-by-step explanation:
The distance traveled by Susanna in one full trip around the rollercoaster can be found using the formula for the circumference of a circle which is given by:
Circumference = π × diameter
Substituting the given diameter of 19 meters into the formula:
Circumference = π × 19 = 3.14 × 19 = 59.66 meters
Therefore, Susanna travels approximately 59.66 meters in one full trip around the rollercoaster.
