The area of any simple shape, such as a circle, triangle or rectangle, can be found by taking a series of measurements from the shape and plugging them into a formula. The necessary formula varies according to the shape but works for all shapes of that type.
Know MoreMeasure the dimensions of the shape. For example, finding the area of a triangle requires the width of the base and the vertical height, whereas finding the area of a circle requires the length of the radius.
Using a math textbook or Internet search, obtain the correct formula for finding the area of the specific shape. Put the measurements into the appropriate formula.
Use the formula to calculate the area of the shape.
The diameter of a circle can be calculated using the formula d = 2r, where "d" indicates the diameter and "r" denotes the radius of the circle. In terms of circumference, the diameter can be computed using the equation d = c/pi, where "c" represents the circumference and pi is approximately equivalent to 3.142. If the area of the circle is given, the formula d = sqrt (4a/pi) can also be used to solve for the diameter, where "a" denotes the area.
Full Answer >To calculate area, first determine the shape of the object. Next, apply the correct formula is needed, and substitute the values into the appropriate places. Finally, the equation should be solved to find the number that represents the area.
Full Answer >The cubic feet formula depends on the shape of the object for which one is calculating volume, but for a cube, v=a^3, where a is the length of one side in feet. For cylinders and prisms, the formula is the area of the base multiplied by the height.
Full Answer >The formula to find the area of a sector is A = N/360 x (pi x r^2). A sector is a section of a circle. In the formula given, A is the area of the sector, N is the degree of the central angle of the sector, pi is an irrational number that can be rounded to 3.14, and r is the length of the radius of the circle.
