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:
${\left(\mathrm{di} a m e t e r\right)}^{2} / 8 \times 20$

If this is not what was meant by the question, please give more details.
