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 5 2 = 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 x (12 / 2) 2 = 3.14159 x 36 = 113.1 cm 2 (square centimeters).
The formula for calculating the surface area of a circle is: Surface Area = πr² Where r is the radius of the circle, and π is the mathematical constant pi (approximately equal to 3.14).
This calculator will calculate the area of a circle given its diameter, using the famous formula area = pi times (d/2) squared. It supports different units such as meters, feet, and inches.
18 mar 2024 · Our surface area calculator can find the surface area of seven different solids. The formula depends on the type of solid. Surface area of a sphere: A = 4πr², where r stands for the radius of the sphere. Surface area of a cube: A = 6a², where a is the side length.
6 lut 2024 · C = circumference. A = area. π = pi = 3.1415926535898. √ = square root. Use this circle calculator to find the area, circumference, radius or diameter of a circle. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns.
To use this formula, simply square the radius of the circle and multiply it by π to obtain the area. For example, if the radius of a circle is 5 units, the area of the circle would be: A = πr² = π(5²) = π(25) = 78.5 square units
