A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
The radius of a circle is equal to half of it's diameter. To convert the diameter into the radius, simply divide it by two.For example: if the diameter is 10, then the radius would be 5
area of a circle (A), radius of circle(R): A=R^2
The radius is half the diameter so the radius is ALWAYS half the diameter. Just because a number is odd doesn't mean you can't take half of it. For example if a diameter is 5 miles, then the radius is 2.5 miles.
Oh, dude, you're hitting me with some math here. So, if the circumference is 44, we use the formula Circumference = 2 * π * radius. Just divide 44 by 2π (which is about 6.28) to get the radius. So, the radius is approximately 7. Oh, the joys of circles and their sneaky circumference-to-radius conversions!
The radius of a circumference is half of the diameter. To find the radius of a circumference with a length of 64cm, you need to divide the circumference by 2π (since the formula for the circumference of a circle is C = 2πr). So, the radius would be 64cm / (2π) ≈ 10.19 cm.
Twice the radius.
It refers to the radius of a circle which is half of its diameter.
radius is half of a circle. when u make a line from the middle of the circle to the edge would be the radius:]
RADIUS
In math, radius is the distance from the center of a circle to any point on the circle. It is half the diameter of a circle.
The radius bone sounds like a math term because "radius" is also a term used in geometry to refer to the distance from the center of a circle to any point on its circumference.
When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.
radius times two
The distance from the center of a circle to its perimeter
you do math
A radius of a circle is half the diameter.
My math teacher said pir2 in other words pi x radius to the second power.
