Keliling = phi x Diameter 314 = 3,14 x diameter Diameter = 314/3,14 = 100cm
Luas = phi x jari jari kuadrat 3,14 x 5x5 3,14 x 25 = 78,5 cm2
Maaf klu salah

Keliling= phi x diameter 314 = 3,14 x diameter Diameter = 100 Maka ; luas = phi x r² = 3,14 x 50 x 50 = 3,14 x 2500 = 7850 cm² Maaf kalau salah
Phi = 3,14 cm
Keliling = phi x Diameter
314 = 3,14 x diameter
Diameter = 314/3,14 = 100cm
Luas = phi x jari jari kuadrat
3,14 x 5x5
3,14 x 25
= 78,5 cm2
Maaf klu salah
