To estimate 43.96 in terms of pi, you can divide 43.96 by the approximate value of pi (3.14). This yields about 14.03, suggesting that 43.96 is approximately 14.03 times pi. For a more precise calculation, using a more accurate value of pi (3.14159) gives approximately 14.00, indicating that 43.96 is roughly 14π.
He estimated pi to 5 decimal places. This estimate was mentioned in Al-Khwarizmi's book on algebra and through that route the estimate arrived in Europe.
You have to calculate the radius - half the diameter. Then square the radius, and multiply by pi (approximately 3.1416). If you want to do a mental estimate, round pi to 3.
Total surface area is about 282.74 units2 (90 pi)(Using pi = 3.14 gives the estimate 282.6)SA = (pi 2r) x h + 2 (pi r2) = 72 pi + 2 (9 pi) = 90 pi

Yes
Zu Chongzhi was the Chinese mathematician who computed the value if pi.
You pronounce it like this: dou pi
use 14.1 times pi pi is close to 3.14159265358979383
You do not need to estimate it. You can calculate it as being pi*r2 which, in this case is pi square cm.
He estimated pi to 5 decimal places. This estimate was mentioned in Al-Khwarizmi's book on algebra and through that route the estimate arrived in Europe.
If you are referring to the Chinese musical plucked-string instrument it is 琵琶 pi(2) pa
2*radius*pi or diameter*pi, pi = 3.14 (rounded to the nearest tenth)
Pi is the never ending, never repeating number. It was created my a Greek mathematician and the estimate for pi is 3.14 but some more digits are: 3.1415926535897932384626433832795028841971693993751058209749445 Pi is the circumference of a circle with a diameter of 1.
