Answer:
167,886,383 basketballs
Step-by-step explanation:
We are asked to find how many basketballs would take to circle around the equator. We have given the earth's radius. So, we need the formula to obtain it's perimeter. Thus:
Earth's diameter is simply radius*2. It means:
On the other hand, we have a basketball crcumference; however, we need to obtain its diameter so that we can later calculate how many basketballs fit on earth's equator by simply dividing earth's circumference by a basketball's diameter.
Diameter of a basketball:
We need to change units to fit in the international system.
29.6 in to cm =
Then:
We have to convert earth's perimeter in km to cm:
Finally, dividing total earth's circumference by a basketball diameter:
