Here's how to calculate the distance around the equator in centimeters:

* Earth's Circumference: The Earth's circumference at the equator is approximately 40,075 kilometers.

* Kilometers to Centimeters: There are 100,000 centimeters in one kilometer (1 km = 100,000 cm).

Calculation:

40,075 km * 100,000 cm/km = 4,007,500,000 cm

Therefore, the distance around the equator is approximately 4,007,500,000 centimeters.
