Formulas used:

Area of a circle: π(diamater/2)²

The volume of a round slab: depth x area

Instructions

1. Find the area of the circle face.

2. Calculate by multiplying measurements together.

*π≈3.1416

Concrete Round column calculator formula

Formulas used:

Volume for under platform: platform depth x (rise height x step count) x width

Volume under each step: run depth x (rise height x number of steps) x width

Instructions

1. Add the total volume under platform + total volume under each step

Concrete Curb and gutter calculator

Formulas used:

Finding the volume under the curb: curb depth x (curb height + flag thickness) x length

Finding the volume under the gutter: gutter width x flag thickness x length

Instructions:

1. Add the total volume under the curb + the total volume under the gutter
