Discover how to calculate area and circumference of a circle with a radius of pi.
504 views
If the radius is π (pi), the calculations for area and circumference of a circle become specific. The area (A=πr²) would be π * π², which simplifies to π³. The circumference (C=2πr) would be 2π * π, simplifying to 2π². Knowing these values helps in practical applications involving geometry and measurement.
