Uses of Pi:
Uses of Pi:
We know that The area of a circle with radius r =πr2.
We also know that the Circumference of a circle with radius r and diameter d =
2πr, or πd
A cool way to calculate Pi:
n
Σ
n = ∞
1⁄n²
1/12+ 1/22+ 1/32+ 1/42+ 1/52. . .
= π2 divided by 6.
The Volume of a cyndrilical solid (cylinder) is equal to:
V = πR2H,
when H = Height, V = Volume, and R = Radius.
