Circumference = (4) x (a quarter of a circle) = (pi) x (the diameter)
Diameter = (4 x quarter-circle) divided by (pi)
Radius = 1/2 the diameter = (2 x quarter-circle) divided by (pi)

How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
How do you find the radious of a circle can you find the circumference?
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
How do you find the area of a circle for 5 th grade?
To find the area of a circle for fifth grade, what one has to do is to first find the radius, the radius is the distance from the central point to all points on the circle, once the radius is found, square the radius. Then multiply the squared radius by pi.
How do you calculate area of circle without radius?
Well, what you do is you would find the circumference, or the distance around the circle.
How to get the formula to find radius in spherometer?
Treat the 3D sphere as a 2D circle. The radius for the sphere is the same radius as for the circle. No matter where on the sphere you place a mark, the distance (radius) from the mark to the centre of the sphere will always be the same as the circle.
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
How do you find out if each point is on inside or outside of the circle?
Find the distance of the point from the centre of the circle. If the distance is - less than that radius then the point is inside the circle, - equal to the radius then the point is on the circle, and - greater than that radius then the point is outside the circle.
How do you find radius of circle?
Measure the distance from the centre of the circle to its circumference.
Find the radius of a circle which has a diameter of 3.6cm?
The radius of a circle is the distance from the center to an outside edge of the circle. The diameter is the distance all the way across the circle. Therefore, the radius is half the value of the diameter.
If you know the length of a radius of a circle how can you find the length of the diameter?
The diameter of a circle is 2 times the radius. The radius of a circle is the distance from any point on the circle to the center of the circle, and the diameter is the distance from one side of the circle to the opposite side, passing through the center.
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
How do you find the radious of a circle can you find the circumference?
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
How do you find the area of a circle for 5 th grade?
To find the area of a circle for fifth grade, what one has to do is to first find the radius, the radius is the distance from the central point to all points on the circle, once the radius is found, square the radius. Then multiply the squared radius by pi.
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
How do you find the area of a quarter circle?
You find the area of the entire circle (pi x radius^2), and then multiply it by 1/4 or 0.25.
How do you calculate area of circle without radius?
Well, what you do is you would find the circumference, or the distance around the circle.
How to get the formula to find radius in spherometer?
Treat the 3D sphere as a 2D circle. The radius for the sphere is the same radius as for the circle. No matter where on the sphere you place a mark, the distance (radius) from the mark to the centre of the sphere will always be the same as the circle.
