How Does It Work? 🤔

This calculator uses basic formulas from geometry to calculate the circle's properties. Simply enter the radius of the circle, and it will instantly display:

1. Area 🔵:

   • Formula: $\text{Area} = \pi \times r^2$
   • The area of a circle is calculated by multiplying pi (approximately 3.14159) by the square of the radius.

2. Diameter 📏:

   • Formula: $\text{Diameter} = 2 \times r$
   • The diameter of a circle is simply twice the radius, which gives the full length across the circle from one edge to the other.

3. Circumference 🌐:

   • Formula: $\text{Circumference} = 2 \times \pi \times r$
   • The circumference is the distance around the circle. It's calculated by multiplying 2 times pi and the radius.

Example:

Let’s say you have a circle with a radius of 5 units:

• Area: $\pi \times 5^2 = 78.54$ square units
• Diameter: $2 \times 5 = 10$ units
• Circumference: $2 \times \pi \times 5 = 31.42$ units

Simply input 5 in the calculator, and you’ll see the exact results for all three properties!
