diameter/2
The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume
Area of circle = pi*(radius)2
The formula for the circumference of a circle is pi * diameter or (2 radius.)
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
It is: 2*pi*radius
diameter/2
Hell are you talking about?!? A radius is a dimension of a circle! A rectangle has no stinking radius!
The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume
this is called finding the circumference. The formula is 2*pie*radius
Area of circle = pi*(radius)2
The formula for the circumference of a circle is pi * diameter or (2 radius.)
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.
It is: (pi*radius)+(diameter)
Area of a circle = pi*radius2
