The milky way has a radius of approximately 50,000 light years. the visible universe has a size of approximately 15 billion light years. if the milky way is represented by an 8 centimeter wide coffee cup , how big would the rest of the universe be in kilometers?

12 km

Step-by-step explanation:

The width of the coffee cup is 8 cm. This is the diameter of the coffee cup. You need to calculate the radius of the coffee cup with this formula:

Where "d" is the diameter.

Sybstitutiing, you get:

Therefore, now you know that 4 cm represents the  radius of Milky Way (approximately 50,000 light years), then the rest of the universe in centimeters is represented with:

From cm to km:

5 pm

step-by-step explanation:

it is 10.6 according to my calculations
