How do you figure out the radius of a circle?
You can divide the diameter by two.
How do you figure out 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.
How do you figure out the circumference of a circle?
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)
What is a figure that has one straight line?
A semicircle is an example of a figure with one straight line. It is a circle that has been split along the diameter.
What is the diameter of a circle that is equal to pi?
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
How do you figure the diameter of a circle that is 5 feet across?
If the circle is five feet across - that is the diameter.
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How do you figure out the radius of a circle?
You can divide the diameter by two.
How do you figure diameter of circle using circumference?
Divide the circumference by pi, and that will give you the diameter.
How do you figure out 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.
How do you figure the area of a circle if you know the diameter?
The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
How do you figure length of a radius?
The radius of a circle is half of its diameter
How do you figure linear footage of circle?
pi times the diameter
How do you figure out the diameter of a circle?
Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.
How do you figure out the circumference of a circle?

How do you figure out circumference and 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.
What the radius of a circle with diameter d 61 yd?
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
