Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
Radius is a line from the center to the outside of a circle or sphere. An example of radius is the spoke a bike wheel. The definition of a radius is a circular limit or a boundary of a specific distance which is drawn from a specific point. An example of radius is a restaurant located within five miles of a house.
Moreover, What is the radius of a circle example?
radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
Secondly, What is the radius for kids?
Radius – The radius is the distance from the center point to the edge of the circle. This is the same distance R we used to make the circle in our definition. So the diameter is two times the radius and the radius is one half of the diameter.
Simply so, What is the radius of a circle?
In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.
What is the radius if the diameter is 12?
First you need to find the radius, the key term to find the radius is diameter=2⋅radius ; therefore the radius r is 122=6 inches. To find the area of a circle, you need to use the formula A=π⋅r2 ; therefore the area A is π⋅62≈113 square inches.

What is Radius and Diameter?
Radius, Diameter and Circumference The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle. So when the diameter is 1, the circumference is 3.141592654
What is the radius equal to?
radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
What is the relationship between a radius and diameter?
Radius, Diameter and Circumference The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center.
How do you explain circle to a child?
A circle is a shape that is made up of a curved line. It’s round, and all points on the curved line are an equal distance from the center point. This shape is two-dimensional, which means it’s flat. The black dot represents the center of the circle.
What is Radius and Diameter of circle?
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

What is the relationship between area and diameter?
Lesson Summary So a diameter is the same as two opposing radii. The formula for the area of a circle is A = π r2, where r is the length of the radius of a circle. We can use our knowledge that a diameter is made up of two radii to understand that r = d/2.
Is radius half of diameter?

How do you explain a shape to a child?
In geometry, a shape can be defined as the form of an object or its outline, outer boundary or outer surface. Everything we see in the world around us has a shape.
How do you find a diameter?
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
Is diameter the same as radius?
The distance from the center of the circle to any point on the circle is called the radius. When two radii (the plural of radius) are put together to form a line segment across the circle, you have a diameter. The diameter of a circle passes through the center of the circle and has its endpoints on the circle itself.
