Area of polygon using radius calculator
Area of polygon using radius calculator
To calculate the area of a polygon using radius, you need to know the number of sides, the length of the radius, and the length of the side. The formula for calculating the area of a regular polygon using the radius is:
Area = (n × r^2 × sin(360/n))/2
Where:
- n is the number of sides of the polygon
- r is the radius of the polygon
- sin is the trigonometric function sine
Here are the steps to calculate the area of a polygon using the radius:
- Determine the number of sides of the polygon.
- Measure the length of the radius of the polygon.
- Measure the length of one of the sides of the polygon.
- Substitute the values of n, r, and s in the formula mentioned above.
- Solve the equation to get the area of the polygon.
Note: If the polygon is not regular, you cannot use this formula to find its area.
Area of polygon using radius
To find the area of a regular polygon using the radius, you can use the following formula:
Area = (n * r^2 * sin(360/n))/2
where:
- n is the number of sides of the polygon
- r is the radius of the polygon
- sin is the sine function
- 360/n is the central angle of the polygon
To use this formula, you need to know the value of n and the radius of the polygon. Then, you can substitute these values into the formula and calculate the area.
