What would be the result of dividing the diameter of a circle into 8 equal parts (expressed as a fraction), squaring the length of one part, and multiplying the result by 20?
I'm going to make a bunch of wild assumptions about what is meant here. If the question is:
Write an expression for converting a diameter into 8 equal lengths and express the result as a simple fraction, then square the numerator of this fraction, then multiply the entire result by 20.
The expression would be:
If this is not what was meant by the question, please give more details.
