Area = 3.1416 x r 2. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Example: The area of a circle with a radius(r) of 3 inches is: Circle Area = 3.1416 x 3 2. Calculated out this gives an area of 28.2744 Square Inches. More Resources... Circle Area Videos Feb 12, 2020 · Calculating a circle's diameter is easy if you know any of the other dimensions of the circle: the radius, the circumference, or the area. It's also possible if you don't know any of the above dimensions but you do have a drawing of the circle. If you want to know how to calculate the diameter of a circle, just follow these steps. The equation for circumference is: The equation for area is: First, we'll find the circumference. The 'r' in the equation stands for radius. The radius of a circle is half of its diameter, so the circle's radius is half of 6--3 inches. So, we can substitute 3 in for 'r' and 3.14 in for Then, we can simply multiply.
Apr 10, 2017 · How To Find The Area Of A Sector Of A Circle If the arc subtends an angle of θ at the centre, then its arc length is Hence, the arc length ‘l’ of a sector of angle θ in a circle of radius r is given by If the arc subtends an angle θ, then … Diameter. The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2r. The Greek letter π. π represents the number Pi which is defined as the ratio of the circumference of a circle to its diameter or π = C / d. For ...
Abjad world foundationHow long does it take to become a detectiveIn geometry, the area enclosed by a circle of radius r is π r 2.Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter. The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. Jul 25, 2014 · Circles Part 1- Understanding Pi, Diameter, Radius and Circumference - Eeris Fritz - Duration: ... Area of a circle, how to get the formula. - Duration: 2:47. mathematicsonline 1,062,368 views. For an example, we have an area of 303,000 square meters. Divide the area (in square units) by Pi (approximately 3.14159). Example: 303,000/3.14159 = 96447.98; Take the square root of the result (Example: 310.56). This is the radius. Now double the radius to get the diameter (Example: 621.12 meters). Start studying *Circumference and Area of a Circle.
