Cara Menghitung Ellipse Area
learn.whatIsHeading
An ellipse is an oval shape defined by two radii: semi-major axis (a) and semi-minor axis (b). Area calculation is simpler than circumference, using a straightforward formula.
Rumus
Area = π × a × b where a is semi-major axis and b is semi-minor axis
Panduan Langkah demi Langkah
- 1Enter semi-major axis a
- 2Enter semi-minor axis b
- 3Multiply π × a × b
Contoh Terpecahkan
Masukan
a = 8 cm, b = 5 cm
Hasil
Area ≈ 126 cm²
π × 8 × 5 ≈ 126
Kesalahan Umum yang Harus Dihindari
- ✕Using major/minor diameter instead of semi-axes
- ✕Forgetting the π constant
