Because you will be using the number pi to find the area of the circle, some rounding will be required.
By using the formula: area of circle = pi*radius2
You get the area by using formulas. There is usually a specific formula to find the area of each shape. Some irregular shaps may not have a formula.

It depends on the number of lumens you get, the more the brighter thus lighting more area.
A 150 watt halogen bulb will give off somewhere around 2000 lumens. These lights may give off up to about 2400 lumens.
3300 lumens is considered fairly bright, suitable for lighting up a medium-sized room or outdoor area. It is equivalent to the brightness of a traditional 200W incandescent light bulb.
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.

Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
From 20,000 to 23,000 lumens depending on the brand.Average figures:Incandescent: 10 lumens per wattHalogen 13 lumens per wattCFL (low-energy) 50 lumens per watt
Approximately 15 lumens per watt for halogen, so 300 lumens.
700 lumens
That will vary on the manufacture and quality of the bulb. There is no set amount of lumens for a 40 watt halogen or any kind of bulb for that matter. To find out the lumen output you need to look at the box it came in as it should be stated. If you don't have the box it may be tricky to find out. You will have to see if you can find the manufacture somewhere on the bulb then google it and check the specs. It's probably safe to say its going to be around 500 lumens on average.
