How to solve for circumference of a circle
WebOct 23, 2011 · #1 Find the Circumference of a Circle Given the Radius Problem: Find the circumference of a circle with a radius of 20 cm. Solution: Plug in 20 for r in the formula C = 2 πr and solve. C = (2) (π) (20) C = 40π C = 125.6 Answer: A circle with a diameter of 20 cm. has a circumference of 125.6 cm. WebFeb 20, 2011 · divide the circumference by 3.14 or pie then divide the answer by 2 then times that answer by itself then times it by pie or 3.14 and you have the area 2 comments ( 7 votes) Show more...

WebThe circumference of a circle is calculated using the formula: 2 x π x radius, where π is a mathematical constant, equal to about 3.14159. It was originally defined as the ratio of a circle's circumference to its diameter … WebDiameter: the largest distance between any two points on a circle; by this definition, the diameter of the circle will always pass through the center of the circle. It is equal to twice the length of the radius. Circumference: the distance around the circle, or the length of a circuit along the circle. Arc: part of the circumference of a circle

WebFeb 3, 2024 · Using the Circumference 1 Write down the circumference formula. The formula is , where equals the circle’s circumference, and equals its radii [2] The symbol ("pi") is a special number, roughly equal to 3.14. You can either use that estimate (3.14) in calculations, or use the symbol on a calculator. 2 Solve for r. WebThe formula for the area of a circle is A = πr2. We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of rto find that r= √13. We find the circumference of the circle with the formula C = 2πr. We then plug in our values to find C = 2√13π. Report an Error
WebSep 29, 2024 · There are two formulas that can be used to calculate the circumference of a circle: C = 2πr or C = πd, where π is the mathematical constant approximately equal to 3.14, [4] r is equal to the radius, and d is equal to the diameter. [5] Because the radius of a circle is equal to twice its diameter, these equations are essentially the same.
WebJul 3, 2024 · You can calculate the circumference of any circle if you know either the radius or diameter. The formulas are: C = πd C = 2πr where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: C = πd C = 3.14 * (8.5 cm) C = 26.69 cm, which you should round up to 26.7 cm neighbors fire alarm going offWebThe circumference of a circle and the area of a circle have one thing in common: the radius. If I were you I'd do it in two steps: - first calculate the radius using the circumference formula, - then calculate the area using the radius you just calculated :-) Hope that helps! 2 comments ( 7 votes) Show more...
