$2 \: \pi \: r$

Area of circle

$\pi \: {r}^{2}$

area of cylinder

C.S.A

$2 \: \pi \: rh$

T.S.A

$\pi \: r \: ({r + h} )$

The exact value of pi is still unknown and it is suspected it's an irrational no.

Step-by-step explanation:

The place-value system, first seen in the 3rd-century Bakhshali Manuscript, was clearly in place in his work. While he did not use a symbol for zero, the French mathematician Georges Ifrah argues that knowledge of zero was implicit in Aryabhata's place-value system as a place holder for the powers of ten with null coefficients.

However, Aryabhata did not use the Brahmi numerals. Continuing the Sanskritic tradition from Vedic times, he used letters of the alphabet to denote numbers, expressing quantities, such as the table of sines in a mnemonic form
