The circle parachute should demonstrate the slowest average descent rate because its natural symmetrical shape would be the most efficient design to maximize wind resistance and create drag.
What keeps a parachute move slower?
The larger the parachute, the greater the drag force. In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.
What causes a parachute to fail?

Do parachutes have a weight limit?
Why Is There a Weight Limit for Tandem Skydiving? In a word, safety. Tandem parachutes are built for two people and these parachutes come with safety recommendations for maximum suspended weight – usually, 500lbs which includes two persons plus gear.
Why do parachutes have holes in the top?
Air resistance or drag pushes against objects when they fall. Parachutes catch a lot of air, creating a lot of drag. … Some parachutes have a hole in the center to release air in a controlled way. It makes the chute more stable, with only a minimal change in drag.
