Use the formula volume = (4/3) pi r3.
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
Area of a circle = pi*radius squared
Do you mean circle? The area of a circle is pi times the radius2.
Use this formula: V = radius2 x Pi x height
You use pi to find volumes that include circles, as volume = area x depth, and the area of a circle always involves pi
Use the formula volume = (4/3) pi r3.
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
use the formula 4/3*π*radius3 to find the volume of a sphere.
Area of a circle = pi*radius squared
Do you mean circle? The area of a circle is pi times the radius2.
Use this formula: V = radius2 x Pi x height
Volume of a cylinder = pi*(radius)2*(height) where pi = 22/7
Volume = pi x r^2, so r^2 = volume/ pi r = sq root(volume/pi).
L × pi × r2
circumference = diameter x pi (pi = 3.14159265 or 3.14 for rough approximation)
Assuming you know the radius - the formula is Pi x Radius2
