So last weeks riddle was:
What has a head, a tail, is brown, and has no legs???
A penny 😉
And this weeks follows on quite nicely if I do say so myself.
You have an empty piggy-bank. Its a perfectly spherical piggy bank with a diameter of 10cm. Assuming a 1pence coin is exactly 1cm in diameter, how many 1penny coins can you fit in this empty piggy bank?
