...whofe bafe is equal to it's perimeter and altitude to the radius of the circle, and the area of the circle is equal to a right-angled triangle, whofe bafe is equal to its circumference and altitude to its radius, it follows (by El. 6. i.) that the area of the circumfcribed... | |

...Circumference) and its Perpendicular (equal the Radius) is equal to the Circle. And confequentlv, a Triangle whofe Bafe is equal to the Circumference, and its Altitude equal to the Radius, is alfo equal to the Circle; for every Triangle is equal to half a Reftangle of the fame Bale and Altitude... | |
