Fore example, today I was walking around Circle Gardens, a small ring road, with 8 houses on it, and I was asked how big is the circle of land, excluding the road?
So I looked up the postcode and popped in the postcode in the "Draw a Circle" tool and took a stab at it's size (50 metres) and then moved the circle to the area and adjusted it to fit, so now I know, it's actually 48.28 Meters
The following list of tools were built by Map Developers taking advange of Google Map

Draw a circle - Enter a radius then click a point or enter an address to draw a circle on a google map.
Elevation Calculator Tool - Works similar to the distance calculator tool, but instead of the distance along the path it shows a graph of elevation points along that path.
Geocode Tool - This tool allows you to enter an address to find the GPS coordinates i.e. latitude and longitude of the address. It also plot the address on a map where it can be moved to adjust the latitude and longitude.
