The radius of a cylinder given its perimeter refers to calculating the radius of the circular base when the total perimeter (circumference plus twice the height) and the height of the cylinder are known.
The calculator uses the formula:
Where:
Explanation: The formula derives from the relationship between the perimeter, height, and circumference of the circular base of the cylinder.
Details: Calculating the radius is essential for various engineering and geometric applications, including volume calculations, surface area determinations, and structural design of cylindrical objects.
Tips: Enter the perimeter and height values in consistent units. Both values must be positive numbers, with height being less than half the perimeter for a valid radius calculation.
Q1: What units should I use for input values?
A: You can use any consistent units (cm, m, inches, etc.) for both perimeter and height, as long as they are the same.
Q2: Can the height be zero?
A: No, the height cannot be zero as it would make the calculation undefined for a cylinder. Height must be a positive value.
Q3: What if the calculated radius is negative?
A: A negative radius indicates invalid input values where the height is greater than half the perimeter, which is not physically possible for a cylinder.
Q4: How accurate is the calculation?
A: The calculation is mathematically exact based on the input values, using the precise value of π for computations.
Q5: Can this formula be used for other shapes?
A: No, this specific formula applies only to right circular cylinders where the perimeter includes both circular ends and the height.
