WebA circle of radius = 2.5 or diameter = 5 or circumference = 15.71 inches has an area of: 1.26645 × 10 -8 square kilometers (km²) 0.0126645 square meters (m²) 126.645 square centimeters (cm²) 12664.5 square millimeters (mm²) 4.88979 × 10 -9 square miles (mi²) 0.0151466 square yards (yd²) 0.136319 square feet (ft²) 19.63 square inches (in²) WebThis is because the diameter is twice the length of the radius. Try an example manually to get the area. Suppose r = 5 inches. a = πr². a = π(25) = 25π. If rounding to the nearest tenth the area is 78.5 square inches. If you know the diameter, simply divide by 2 to get the radius and use the same formula as above.
WebDescription: The radian is an SI derived unit of angle, commonly used in maths and engineering. A radian measures approx. 56.296 degrees (when the arc length is equal to the radius). Definition: The angle made by taking the radius of a circle and wrapping it along the circle's edge. Therefore 1 Radian is equal to (180/π) degrees Origin: WebDiameter 10 = radius 5 Circumference of the Circle- Radius = 2.

If R = 2, then C = 4π, and if D=2, C = 2π both are exact answers. ( 0 votes) Show more... Muhammed 3 years ago
WebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd.
WebIt's simplest to convert circumference to radius first, then find the circle's area: r = (c/2\pi) \\ a = \pi r^2 r = (c/2π) a = πr2 Using the Circumference Calculator You can enter the circumference and also compute radius and diameter in mils, inches, feet, yards, miles, millimeters, centimeters, meters and kilometers. churchill towers aptsWebEverbilt 3-inch with 1/4-inch Radius Black Door Hinge (2-Pack) Model # 859-567 Store SKU # 1000773085 (11) Write a Review; Q&A (1) Overview.
