A 14-sided ball is referred to as a tetradecaheron. In geometry, a ball typically refers to a three-dimensional object, while a tetradecaheron is a polyhedron with 14 faces. However, it’s worth noting that such shapes can be complex and may not have a common practical application or representation.

A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 541, exactly as in the question.
It's a good idea to go to court when you are summoned. Make sure you have adequate representation, if possible.
The base makes no difference. The symbol 1, by itself or with leading zeroes, is always regarded as being the number one. Note that 1 is not a number. One (the word) is a number while 1 is merely the symbolic representation for the number we call one. But 01 is also one, as is 000000001. The leading zeroes are simply ignored.
