Thickness for walks
Four inches is the usual thickness for a residential walk that only sees foot traffic. Where the walk crosses a driveway, pour that section at 6 inches, since car tires will cross it.

Joints along the walk
Tool a control joint about every 6 feet, matching the width, which gives roughly 4 joints along this walk. Add an isolation joint where the walk meets the house, steps or a driveway so the slabs can move independently.
Truck, bags or a short load
This is past the point where bags are practical; call a ready-mix plant. If the truck cannot reach the far end of the walk, plan for wheelbarrows or a chute extension; see how far a concrete chute reaches.
Slope and finish
Slope the walk a little to one side for drainage and finish it with a broom for traction. Round the edges with an edging tool so they chip less.
