Halimbawang may solusyon
A circle with radius 5
Diameter = 2 × 5 = 10.
Circumference = 2π × 5 = 10π ≈ 31.415927. Area = π × 5² = 25π ≈ 78.539816.
Mga madalas itanong
Why is the answer written with π?
π is irrational, so “25π” is the exact answer. The decimal below it is rounded.
What units should I use?
Any unit works. Lengths come out in the same unit; area comes out in that unit squared.
