How can you calculate the radius of a circle?

To find the radius from the circumference of a circle, you have to do the following:

1. Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter.
2. Divide the diameter by 2.
3. There you go, you found the circle’s radius.

How do you find the radius of a circle in feet?

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.

What is the radius of 18 ft?

Dean R. The diameter is twice the radius, so would be 36 feet.

63 meters

Therefore, when you ride a circle with a diameter that is the width of the arena, you are riding a 20-meter circle. By definition the circle’s diameter is 20 meters; the center point is located on the centerline of the arena, the radius of the circle is 10 meters (33′) and the circumference is 63 meters.

How do you find the radius of a circle with the circumference?

Video quote: The radius length of a circle is the distance from the center to any point on the circle. Which is necessarily half of the diameter. And so of course the diameter multiplying. Both sides of this

How do you find the radius of a circle if you have the area?

To find the radius, divide the area by pi, then take the square root.

How do you find the radius and diameter of a circle?

Video quote: We'll just look at another example as well this time we've been given the area and we want to find the diameter. So again we have a formula for the area it's the area of a circle is equal to PI
