The moon is a sphere that does not give off light of it's own. Rather, moonlight is caused by the sun's reflection off the moon.
The circumference of the Earth around the equator is 24901.45 miles, but since it's not a perfect sphere, measuring around another route, will give you a different answer.

There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6There is a function called ROUND, which enables you to round values to a specified amount of digits:=ROUND(2302.5543,2) would give 2302.55There are two other functions called ROUNDDOWN and ROUNDUP that can be used to round figures down or up with a set amount of decimal places.=ROUNDDOWN(2302.57,1) would give 2302.5=ROUNDUP(2302.52,1) would give 2302.6

The sun give light to the star because the sun reflects on the star to give them light.
