Answer to Problem 1VSC

Solution: The diameter of star Aldebaran would be approximately 6metres

Explanation of Solution

Introduction: Size of the giant star Aldebaran is 30 times larger than the size of the Sun.

Given that size of Sun is about the size of a grapefruit.

Thus, size of Sun is in between 0.1m to 0.2m .

Also, we know that size of star Aldebaran is 30 times larger than the size of the Sun.

Thus, the size of star Aldebaran would range from 3m to 6m .

Hence, the diameter of star Aldebaran is approximately 6m .

Conclusion: Hence, diameter of star Aldebaran would be approximately 6 m .
