Is the radius of a circle a function of its area?
You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)
What is half of a diameter of a circle called?
The radius of the circle.
Which term describe the distance from the center of a circle to any point on the circle?
The distance from the center of a circle to any point on the circle is called the radius of the circle. The radius is a line segment that starts at the center of the circle and ends at any point on the circle. It is always a straight line and is always perpendicular to the circumference of the circle. The radius is half the diameter of the circle, which is the distance across the circle through the center. The diameter of a circle is always twice the length of the radius.

How do you calculate the radius of a circle?
The radius of a circle is half of its diameter.
What is a radius circle?
If you mean "what is the radius of a circle", then the answer is the line segment or length from the center of circle to the set of points that form the circle. The radius is also half of the diameter.
What is the area and circumference of 30.5meters using 3.14 having a solution?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi

What is half of a diameter of a circle called?
The radius of the circle.
Wha is the radius of a circle?
The radius of a circle is half the circle's diameter
What is the radius of a circle where d is the diameter of the circle?
the radius of a circle is r
If the circumference of the circle is 75.36 what is the radius?
Divide the circumference by the value of Pi - then divide that answer by 2, and you'll have your solution.
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
Which is the best defeniton of the radius and and of a circle?
The radius of a circle is halve the circle's diameter.
What is the distance from the centre of a circle to any point on the circle?
It is the radius of the circle.
What is the equation for the radius of a circle?
The radius of a circle = the diameter of the circle divided by 2
How do the the radius and diameter of a circle compare?
The diameter of a circle is twice its radius
