Learn how to calculate the area of a circle using the formula A = πr2, where r is the radius. See the derivation of the formula using rectangles and triangles, and examples of real-life applications of circles.
- The area of circle is the region occupied by circle in the two-dimensional space.
- The area of circle can be calculated by using the formulas: Area = π x r 2 , in terms of radius ‘r’. Area = (π/4) x d 2 , in terms of diameter, ‘...
- The perimeter of circle is nothing but the circumference, which is equal to twice of product of pi (π) and radius of circle, i.e., 2πr.
- Given, r = 3 cm. We know that the area of circle is πr 2 square units Hence, A = π x 3 2 = 9π cm 2 .
- We know that the circumference of a circle is 2πr units. Hence, C = 2π(14) = 28π cm.
- We know that, Area of a circle = πr 2 square units Hence, 340 =3.14 r 2 Hence, r 2 = 340/3.14 r 2 = 108.28 Hence, r = 10.4 cm. Hence, radius o...
- We know that, Area = πr 2 A = π(6) 2 A = 36π Hence, the area of a circle is 36π, if the radius is 6 cm.
- The area of a circle is 1303.8 square inches if its circumference is 128 inches.
Learn how to calculate the area of a circle using the formula A = πr 2 or A = (π/4)d 2, where r is the radius and d is the diameter. See the derivation, real-world examples, and differences between area and circumference of a circle.

Learn how to calculate the area of a circle using the formula A = π r2 or A = (π/4) × D2. Use the online calculator to find the area, radius, diameter or circumference of a circle.
Although often referred to as the area of a circle in informal contexts, strictly speaking the term disk refers to the interior region of the circle, while circle is reserved for the boundary only, which is a curve and covers no area itself.
Area of a Circle Formula. The area of a circle is the total amount of space enclosed by its boundary or circumference. There is no volume in a circle because it is a flat, two-dimensional shape. If you know the radius of a circle, you can easily find its area.
