The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume
Area of circle = pi*(radius)2
A radius is half of the diameter of a circle, or the distance from one endpoint to the center.
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
1 1/2 times the nominal pipe size
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 the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.

this is called finding the circumference. The formula is 2*pie*radius
Area of circle = pi*(radius)2
A radius is half of the diameter of a circle, or the distance from one endpoint to the center.
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
The formula for the circumference of a circle is pi * diameter or (2 radius.)
