The formula to calculate the engine displacement is:
\(ED = \frac{\pi}{4} \times D^2 \times S \times N\)
Where:
Example 1:
Calculation:
\(ED = \frac{\pi}{4} \times 80^2 \times 90 \times 4 = \frac{3.14159}{4} \times 6400 \times 90 \times 4 \approx 1809557 \text{ cc}\)
Example 2:
Calculation:
\(ED = \frac{\pi}{4} \times 85^2 \times 88 \times 6 = \frac{3.14159}{4} \times 7225 \times 88 \times 6 \approx 2994618 \text{ cc}\)
