A reciprocating compressor cylinder has a 10 inches bore and 14 inches stroke. The volume of refrigerant, in cubic inches, will be closer to:

Explanation:
Displacement of a reciprocating cylinder is found by multiplying the bore’s cross-sectional area by the stroke. For a circular bore, area = π*(d/2)^2. With a 10-inch bore, the radius is 5 inches, so the area is π*25 ≈ 78.54 square inches. Multiply by the 14-inch stroke: 78.54 × 14 ≈ 1099.6 cubic inches. The refrigerant volume is about 1100 cubic inches, so the closest choice is 1099.
