luas lingkaran 7.546 cm² berapakah panjang diameter dan panjang jari jari dari lingkaran tersebut? tolong dijawab ya pake cara soalnya besok mau dikumpul
![]()
JARI - JARI ↓
L = πR²
7546 = 22/7R²
R² = 22/7 ÷ 7546
R² = 7/22 × 7546
R² = 7(7546/22)
R² = 7(343)
R² = 2.401
R = √2401
R = √49²
R = 49 CM
DIAMETER ↓
D = 2(R)
= 2(49)
= 98 CM
L = πr²
7.546 cm² = 22/7 × r²
r² = 7.546 ÷ 22/7
r² = 7.546 × 7/22
r² = 52.822/22
r² = 2.401
r = √2.401
r = 49 cm
- jari-jari = 49 cm
diameter:
d = 2 × r
d = 2 × 49
d = 98 cm
