Area = Pi x 3^2 = 9Pi square units. Answer Save. 3.94476 × 10 5 square inches (in²) Use the this circle area calculator below to find the area of a circle given its circumference, or other parameters. 4 Answers. circumference = 2 * pi * radius. well if the formula for area is π*r^2 . The area (A) of a circle is how much space the circle takes up or the region enclosed by the circle. Radius = Diameter / 2 = 6 / 2 = 3. Use this circle calculator to find the area, circumference, radius or diameter of a circle. The circumference (C) of a circle is its perimeter, or the distance around it. A circle is the set of all points in a plane that are a fixed distance, called the radius, from a fixed point, called the center. Conclusion : The unit of the circumference is the same as the unit of. √ = square root Calculator Use. Anonymous. More generally, the perimeter is the curve length around any closed figure. Length width distance breadth height perimeter circumference is measured plain units like cm, feet etc. Units: Note that units of length are shown for … Area of a circle is defined as π r2 and the diameter as 2r. any specific unit, the circumference is in centimeters too. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. To calculate the area, you just need to enter a positive numeric value in one of the 3 fields of the calculator. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns. The circumference of the circle -- the line around the outside of the circle -- can be calculated in the same way. Believe it or not, that percentage is 78.5% again. If radius is in centimeters, as (2 * pi) is a number without . Circumference may also refer to the circle itself, that is, … It is also called as the longest chord of the circle. Diameter = Circumferece / ? Notice that here, the radius of our circle is 2 units. Circumference or perimeter of a circle is defined as the distance around it. So we have (2)(π)(2) which is equal to 4π units. Answer: 12.56 units Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference of a circle which is shown below. Diameter = Circumference / Pi = 6Pi / Pi = 6. Area of a circle = π r². This online diameter to circumference converter helps you to find the perimeter value from the given diameter at desired units. what is the circumference of a circle if the area is 1384.74 units squared? ... the formula is pi x radius squared (?r²) yet with the intention to try this, you should first locate the diameter. The circumference of the circle is just a percentage of the circumference (perimeter) of the square, and it's the same percentage no matter what the size. So the circumference is 14π units. Relevance. 10 years ago. 6 years ago. Volumes are measured in cubic units like cm³, feet³ etc Circumference of (the same) circle = 2 π r. given the area, solve for r...then calculate the circumference [your teacher has given you an 'approximation' for π ] Areas are measure in square units like cm², feet² etc. Guest Aug 17, 2017 #2 +178 +1 . ***** So we can plug in 2 for r in the formula. Hope that helps :) 0 0? In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. Both area and perimeter can be calculated with simple formulas using … The diameter of a circle is the straight line passing through the center of the circle. Circumference. The area is measured in units units such as square centimeters $(cm^2)$, square meters $(m^2)$, square kilometers $(km^2)$ etc. Plugin the value and you can solve problem c.
