Radius Of A Circle Calculator
What is a radius?
A radius is a straight line from the centre of a circle to any point on its edge. It tells us how far away that point is from the centre.
How do I find the radius of a circle?
To find the radius of a circle, you can use the formula: radius = diameter ÷ 2. The diameter is the distance across the circle through its centre.
What’s the difference between diameter and radius?
Diameter is the distance across the circle through its centre, while the radius is the distance from the centre to the edge. You can find the radius by dividing the diameter by 2.
Can I calculate the radius if I only have the circumference of the circle?
Yes, you can. If you know the circumference (the distance around the circle), you can use the formula: radius = circumference ÷ (2 × π), where π (pi) is approximately 3.14159.
Why is knowing the radius important?
Knowing the radius of a circle helps in many real-life situations, like calculating the area or circumference of a circle, designing circular objects, or understanding the dimensions of circular patterns in nature or man-made structures.
