What is the diameter of 12 feet?
Question 328630: how to solve this? what is the length,in feet, of the circumference of a circle whose diameter is 12 feet? feet, which is approximately 37.68 ft.
How do you convert circumference to radius?
To find the radius from the circumference of a circle, you have to do the following:
- Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter.
- Divide the diameter by 2.
- There you go, you found the circle’s radius.
What is the circumference of a plate with a radius of 5 cm?
Explanation: The formula for the circumference of a circle is 2πr so all we have to do is plug in 5 for our radius: 2π(5) which can be simplified to 10π .
What is the circumference if radius is 5?
31.416 units
Is diameter a chord?
(a) Yes , every diameter of a circle is a chord.
Is diameter the longest chord?
A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle.
Is a radius also a chord?
Any segment which connects two different points on a circle is a chord. The radius of a circle connects the centre and one point on the circle. Hence a radius cannot be called a chord.
Is the radius always half of the diameter?
The center of a circle is the midpoint of its diameter. That is, it divides it into two equal parts, each of which is a radius of the circle. The radius is half the diameter.
How do you find the diameter of a circle from a chord?
The chord of a circle which passes through the centre of the circle is called the diameter of the circle. The diameter of a circle is the distance across a circle. The diameter is also the longest chord of a circle. Diameter of a circle d = 2r, where r is the radius of the circle.
What is a radius in 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.
