Area Equation. If you know the radius, r r, in whatever measurement units (mm, cm, m, inches, feet, and so on), use the formula π r 2 to find area, a a: The areas of the triangular faces will have different formulas for different shaped bases.

In strictly correct mathematical wording the formula above should be spoken as s raised to the power of 2, meaning s is multiplied by itself. Area = π r 2: Area = ½ × b × h.
Area Is Measured In Square Units Such As Square Inches, Square Feet Or Square Meters.
Sometimes, base and height are used instead of length and width. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Learn more about area, or try the area calculator.
But We Usually Say It As S Squared.
The area, a, of a rectangle is the product of its length, l, and width, w. Area = 1/ 2 b×h: Area of a square = side times side.
Area = 4 × Π × 4 ² = 4 × Π × 36 = 452 Cm ² (1.3)
The area of a figure is the number of unit squares that cover the surface of a closed figure. Let us consider a square as a rectangular object whose length is of a unit and breadth is of a unit. A = sides of the square:
Area = Π R 2:
Area of a triangle = a = ½ (b × h) square units where b and h are the base and height of the triangle, respectively. Learn more at area of plane shapes. Where s is the length of one side.
Since Each Side Of A Square Is The Same, It Can Simply Be The Length Of One Side Squared.
A = π r 2 2 to find the area of a semicircle with diameter, divide the diameter by 2 to find the radius, and then apply the area of a semicircle formula. The width is 5, and the height is 3, so we know w = 5 and h = 3: If you know the radius, r r, in whatever measurement units (mm, cm, m, inches, feet, and so on), use the formula π r 2 to find area, a a:
