Proposition IV.

The Circumference of a Circle being given to find the Superficial Content.

As the Square of the Circumference of a Cir∣cle given is to the Superficial Content of that Circle: so is the Square of the Circumference of another Circle given to the Superficial Con∣tent required. Example, As the Square of 3.14159 is to 7853938: so is 1. the Square of another Circle to 079578 the Superficial Content required, and so an Unite for the most easie work∣ing may be brought into the first place: Thus the given Circumference being 41. 626. I say,

As 1. to 0.79578: so is the Square of 41.626 to 137.88 the Superficial Content required.
