# Good Karma Domes - Estimate Builder

## Welcome to the GoodKarmaDomes Estimate Builder

Before we begin, you will need two things:- You will need to have JavaScript enabled on your browser (usually is).
- You will need to know the mileage from where you want the dome built to Oklahoma City (for delivery charges). You can find this out by going to www.mapquest.com and entering your location.

All domes are 4 frequency hemispheres. Included is nuts and bolts, and instructions for assembly. Delivery prices are based on kit size and mileage. This estimate is only a general estimate for idea building and not a contract price.

## Useful Math

- Pi π
- 3.1416
- Circumference of circle (or perimeter)
- Pi*d or Pi*2*r where d=diameter r=radius
- Area of circle (or square footage)
- Pi*r*r = (
**π**r^{2}) - Area of Sphere (or skin or roofing)
- 4*Pi*r*r =(4
**π**r^{2}) for hemisphere 2*Pi*r*r = (2**π**r^{2}) - Volume of Sphere (or interior cubic footage used for calculating HVAC)
- 4/3 * Pi *r*r*r (4
**π**r^{3}/3) - for hemisphere = 2/3 * Pi *r*r*r = (2
**π**r^{3}/3) - note: by doubling the diameter of a sphere, the surface area is increased by a factor of 4; the volume is increased by a factor of 8
