oh yeah and then:

Convert your answer to the previous question to find the Moon's size in arc-minutes (')

Give your answer to the nearest arc-minute (no decimal places)

Your answer should be close to the equivalent of 1/2 degree.

## Need help please

This question has been giving me grief all morning, could anyone help me out:

If the moon's diameter is 3,476 km and its average distance from Earth is 384,000 km, use the small angle formula to calculate the Moon's size in the sky.

angular size / 206,265" = diameter/ distance

Report your answer to the nearest arc-second (")
