Learn how to calculate the area of a circle using the formula A = πr2, where r is the radius and π is pi. See the derivation of the formula using rectangles and triangles, and find examples and FAQs on area of circle.
- 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.
Free online area of a circle calculator which helps you calculate the are of any circle, given its radius. Supports many different metrics such as in, ft, yd, mm, cm, meters, etc.
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.
The area of a regular polygon is half its perimeter multiplied by the distance from its center to its sides, and because the sequence tends to a circle, the corresponding formula–that the area is half the circumference times the radius–namely, A = 1 / 2 × 2πr × r, holds for a circle.
Understand that you can easily determine the area of a circle using the formula Area = π × r^2, where π is approximately 3.14, and r represents the radius of the circle. Note that radius is half the diameter of a circle.
