Three common formulas that use pi (π) are: The circumference of a circle, given by the formula ( C = 2\pi r ), where ( r ) is the radius. The area of a circle, calculated using ( A = \pi r^2 ). The volume of a cylinder, which is found using ( V = \pi r^2 h ), where ( h ) is the height of the cylinder.

9 √(2/pi) We start with the formulas for surface area (4 pi r^2) and volume (4/3 pi r^3). If 4 pi r^2 = 18, then r = 3/√(2 pi); plug that into the formula for volume and we get 9 √(2/pi) as the answer.

I know what it is
Pi (π) is not derived from a single mathematical formula but is often approximated using various methods. One of the most famous formulas is the Leibniz formula for π, which states that π can be calculated as π = 4 * (1 - 1/3 + 1/5 - 1/7 + 1/9 - ...). Another notable method is the use of the circumference-to-diameter ratio of a circle, which defines pi as the constant ratio. Additionally, more complex series and products, such as the Bailey-Borwein-Plouffe formula, also provide ways to calculate π.
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2 Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2 Total surface area of a cylinder = (2*pi*radius2)+(2*pi*radius*height)
