Question

3. The largest non-planet objects in our solar system, are our own Moon (radius=1738 km), Io (1810 km), Eris (1,500 km), Europa (1480 km), Ganymede (2600 km), Callisto (2360 km), Makemake (800 km),Titan (2575 km), Triton (1350 km), Pluto (1,200 km), Haumea (950 km). Create a bar chart on a separate piece of paper that orders these bodies from smallest to largest. In the space provided below, what is the: A)verage radius? B) Median radius?​

Answer 1

The average radius of the listed non-planet objects in the solar system is 1,760.27 km. The median radius, when listed from smallest to largest, is the radius of Europa, which is 1480 km.

Step-by-step explanation:

To calculate the average radius of the non-planet objects, we add all the radii and divide by the number of objects:

(1738 + 1810 + 1500 + 1480 + 2600 + 2360 + 800 + 2575 + 1350 + 1200 + 950) km / 11

= 19,363 km / 11

= 1,760.27 km.

The median radius is the middle value when the radii are listed in order. So, first we order them from smallest to largest:

• Makemake (800 km)
• Haumea (950 km)
• Pluto (1200 km)
• Triton (1350 km)
• Eris (1500 km)
• Europa (1480 km)
• The Moon (1738 km)
• Io (1810 km)
• Titan (2575 km)
• Callisto (2360 km)
• Ganymede (2600 km)

Since there are 11 objects, the median radius is the sixth one in the list, which is Europa with a radius of 1480 km.
