The diameter of the ic 1101 is 50 times larger than the diameter of the Milky Way
A diameter is a line that passes through the center of a circle or sphere and touches either end of the circle.
To determine how many times larger the diameter of the ic 1101 is greater than the diameter of the Milky way, we would divide the diameter of the ic 1101 by the diameter of the Milky way
Diameter of the ic 1101 / diameter of the Milky way
5x10^22 ÷ 1x10^21
5 ÷ 1 = 5
10^22 - 10^21 = 10^1
5 x 10^1 = 50
