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.)
To find the outside diameter of a pipe with a circumference of 870 mm, you can use the formula for circumference, which is C = πd, where C is the circumference and d is the diameter. Rearranging the formula gives d = C / π. Substituting the values, the diameter is approximately 870 mm / 3.14, which is about 277.5 mm. Therefore, the outside diameter of the pipe is approximately 277.5 mm.
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
Circumference of a circle = (pi) x (diameter)
Divide the circumference by 2*pi because 2*pi*radius = circumference

4*pi*r2. because surface area is equal to circumference of circle.
Circumference = 2 x pi x radius
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
