That is the first term. Divide the first term by 3 to obtain the third and so on and thus get further terms. Divide the terms, in order, by the odd numbers 1, (3, 5) etc. Add the odd-order terms to and subtract the even-order terms from the preceding. The result will give the circumference’.¹ - [Previous: c8.s6.45](https://indike.org/pramana/ins.science.sarma-1972.c8.s6.45) - [Next: c8.s6.47](https://indike.org/pramana/ins.science.sarma-1972.c8.s6.47) - [Up: c8.s6](https://indike.org/pramana/ins.science.sarma-1972.c8.s6) --- Source: [https://indike.org/pramana/ins.science.sarma-1972.c8.s6.46](https://indike.org/pramana/ins.science.sarma-1972.c8.s6.46) · Pramāṇa
