What is the formula for finding the circumference of a circle with diameter?
PI times the DIAMETER
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
What is the formula for finding circumfernce?
circumference of a circle = 2*pi*radius or pi*diameter
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
What is the formula for finding the diameter when you only have the area?
If Area of a circle = 2 * pi * rAnd Diameter = 2 * rTherefore:Diameter = 2 * r= Area of circle / piwhere pi = 3.14
What is the formula for finding the circumference of a circle with diameter?
PI times the DIAMETER
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
What is the formula for finding circumferencE when only diameter is given?
Circumference of a circle = (pi) x (diameter)
What is the mathematical formula for finding the radius of a circle?
To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What is the formula for finding the diameter with the area?
If Area of a circle = (2)(pi)(r), and diameter = 2r, then: diameter = 2r = Area of circle / pi, where pi = 3.14
What is the formula for finding the area of a circle when you know the diameter?
D=Diameter, pi=3.14159... Area of circle = (D/2)2 * pi
What is the formula for finding the circumferance of a circle?
Either pi times the diameter or pi times twice the radius (which is the diameter)
Formula for finding the circumference of cone?
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
What is the formula for finding circumfernce?
circumference of a circle = 2*pi*radius or pi*diameter
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
What is the formula for finding the perimeter of a semicircle?
Half the Circumference + the DiameterCircumference of a circle = pi X d ,so perimeter of a semi-circle = (3.142 X Diameter) + Diameter
