To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
3.1416 times. This figure is normally known as pi.
Yes, it is. Hint, always remember to check that the figure given in the problem is the radius., and not the diameter. If it is the diameter, then the radius is half that.
The radius is half of the diameter of a circle.
Perimeter of what? A circle diameter times Pi. Another shape the sum of all sides.
If the circle is five feet across - that is the diameter.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
You can divide the diameter by two.
Divide the circumference by pi, and that will give you the diameter.
Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.
The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
pi times the diameter
The radius of a circle is half of its diameter
Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)
2 times pi times radius
The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.
The radius of a circle is equal to half of it's diameter. If you want to figure out the radius from a given diameter, simply divide the diameter by two:Radius = Diameter / 2Radius = 61 / 2Radius = 30.5 yd
