These theorems (results) have overcome some limitations of previous existed formulas; now no need to calculate radius for a circle if only circumference is given and no use of trigonometry (sine, tangent and co
The area of a circle is:π (Pi) times the Radius squared:A = π r2 or, when you know the Diameter:A = (π/4) × D2 or, when you know the Circumference:A = C2 / 4πExample: What is the area of a circle with radius of 3 m ? Radius = r = 3 Area= π r2 = π× ...
Task 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 52 = 3.14159 x 25 = 78.54 sq in. Task 2: Find the area of a circle given its diameter is 12 cm. Apply the second equation to get π...
The area of a circle calculator helps you compute the surface of a circle given a diameter or radius. Our tool works both ways— no matter if you're looking for an area-to-radius calculator or a radius to the area one, you've found the right place ◔ We'll give you a tour of ...
Area of a circle using the radius Given the radius of a circle, the formula for calculating the area of a circle states that: Area of a Circle = πr2 square units A = πr2 square unitsWhere A = the area of a circle. pi (π) = 22/7 or 3.14 and r = the radius of a circle...
