AREA AND PERIMETER OF ELLIPSE / LUAS DAN KELILING OVAL
Area and Perimeter of Ellipse Calculator
Kalkulator Luas dan Keliling Oval
Area of Ellipse Formula:
Rumus Luas Oval:
Perimeter of Ellipse Formula:
Rumus Keliling Oval:
For Example / Contoh:
Calculate the area and Perimeter of the Ellipse where the major radius is 12cm and minor radius is 9cm.
Hitunglah Luas dan Keliling Oval yang kedua jari-jarinya adalah 12cm dan 9cm!
Solution / Jawaban:
Area / Luas
$a=12$
$b=9$
$A=πab$
$=3.14×12×9$
$=339.12$
Perimeter / Keliling
$a=12$
$b=9$
$P\approx 2π\sqrt{\frac{a^2+b^2}{2}}$
$\approx 2×3.14\sqrt{\frac{12^2+9^2}{2}}$
$\approx 6.28\sqrt{\frac{144+81}{2}}$
$\approx 6.28\sqrt{\frac{225}{2}}$
$\approx 6.28×10.61$
$\approx 66.63$

Rumus Luas Oval:
$A=πab$
Perimeter of Ellipse Formula:
Rumus Keliling Oval:
$P\approx 2π\sqrt{\frac{a^2+b^2}{2}}$
Or
$P\approx π[3(a+b)-\sqrt{(3a+b)(a+3b)}]$
Or
$P\approx π[3(a+b)-\sqrt{(3a+b)(a+3b)}]$
For Example / Contoh:
