If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
What is the equation for the radius of a circle?
The radius of a circle = the diameter of the circle divided by 2
How many radii of a circle will equal its circumference?
Well, the equation for finding the circumfrence of a circle is (diameter)(pi). That is diameter times pi. since the diameter of a circle is 2 radii, we can say that there is 2(pi) radii in a circle.
If the diameter of a circle is 5 what is the circumference?
The equation for determining the circumference of a circle is circumference = pi x diameter. So if the diameter is 5, then the circumference is pi * 5 = 15.71
What is the mathematical equation you generally use to find the circumference of a circle when you know the diameter?
circumference of a circle = diameter*pi or 2*pi*radius
If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
What is the equation for the radius of a circle?
The radius of a circle = the diameter of the circle divided by 2
What is the equation for the diamiter of a circle?
Diameter = 1/2 of the circle's radius. Diameter = 2 times the square root of (the circle's area/pi) Diameter = the circle's circumference/pi
What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
How many radii of a circle will equal its circumference?
Well, the equation for finding the circumfrence of a circle is (diameter)(pi). That is diameter times pi. since the diameter of a circle is 2 radii, we can say that there is 2(pi) radii in a circle.
If the diameter of a circle is 5 what is the circumference?
The equation for determining the circumference of a circle is circumference = pi x diameter. So if the diameter is 5, then the circumference is pi * 5 = 15.71
What is 7 ft diameter insq ft?
If you are referring to a circle, divide the diameter by 2 (to get the radius), then use the standard equation for the area of a circle. For your reference, this is the equation: area = pi x radius2
What is the mathematical equation you generally use to find the circumference of a circle when you know the diameter?
circumference of a circle = diameter*pi or 2*pi*radius
If the radius of a circle is 8 what is the diameter?
If the radius of a circle is 8, then the diameter is 16. The diameter of a circle is two times of a radius The equation would be d = 2r so plugging in 8 for r, the equation would become d = 2(8) Therefore d is 16.
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
Equation to find the area of a circle?
Area of a circle = (pi) (R2)R = radius of the circle = 1/2 of its diameter
How do you find the area of a circle using its diameter?
The area of a circle is pi(radius)2 Radius is half the diameter. Simply divide the diameter in half and enter it into the equation 3.14(diameter/2)2
