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 many times does a diameter of a circle fit around that circle?
3.1416 times. This figure is normally known as pi.
What is Pi r squared is it the area of a circle?
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.
What is half of a diameter of a circle?
The radius is half of the diameter of a circle.
Can you give me a figure to find the perimeter?
Perimeter of what? A circle diameter times Pi. Another shape the sum of all sides.
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 linear footage of circle?
pi times the diameter
How do you figure length of a radius?
The radius of a circle is half of its diameter
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)
How do you figure the diameter of a circle?
2 times pi times radius
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.
How do you figure permiter of a circle?
The perimeter of a circle is its circumference and it found by 2*pi*radius or pi*diameter
