Circle Calculator
Enter the radius of the circle to calculate its area, circumference, and diameter.
Steps for Calculation
- Input Radius:
- Enter the radius of the circle (e.g.,
5
).
- Enter the radius of the circle (e.g.,

Detailed Description
- Area:
- The area of a circle is calculated using the formula:Area=πr2Area=πr2Where rr is the radius of the circle.
- Example: For a radius of
5
, the area is π×52≈78.54π×52≈78.54.
- Circumference:
- The circumference of a circle is calculated using the formula:Circumference=2πrCircumference=2πrWhere rr is the radius of the circle.
- Example: For a radius of
5
, the circumference is 2×π×5≈31.422×π×5≈31.42.
- Diameter:
- The diameter of a circle is calculated using the formula:Diameter=2rDiameter=2rWhere rr is the radius of the circle.
- Example: For a radius of
5
, the diameter is 2×5=102×5=10.
