A better value of π is found in the \*Mānava Sulba\*, which states that a square of two by two cubits is equivalent to a circle of radius 1 cubit and 3 aṅgulis.² Whence (4) π=4(8/9)²=3·16049 This value was given before by the Egyptian Ahmes (\*c.\* 1500 B.C.). With Dvārakanātha's corrections we have π=4/(\[1+⅓(√ 2-1)\]²)(118/117)²=3·141109... π=4(1-⅛+1/8.29-1/8.29.6+1/8.29.6.8)² ×(1+½·3/133)² =3·157991... - [Previous: c16.83](https://indike.org/pramana/ins.science.datta-1932.c16.83) - [Next: c16.85](https://indike.org/pramana/ins.science.datta-1932.c16.85) - [Up: c16](https://indike.org/pramana/ins.science.datta-1932.c16) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c16.84](https://indike.org/pramana/ins.science.datta-1932.c16.84) · Pramāṇa
