Here's how to figure out the difference in radius between Earth and Venus:

* Earth's Radius: Approximately 6,371 kilometers (3,959 miles)

* Venus's Radius: Approximately 6,052 kilometers (3,761 miles)

Calculation:

1. Divide Earth's radius by Venus's radius: 6,371 km / 6,052 km = 1.053

Answer: Earth's radius is approximately 1.053 times greater than Venus's radius.

In other words, Earth's radius is about 5.3% larger than Venus's radius.
