Penjelasan dengan langkah-langkah:
1. D = K / π = 308 ÷ 22 × 7 = 98 cm
r = D / 2 = 49 cm
2. K = πD = 3.14 × 24 = 75.36 cm
r = D / 2 = 24 / 2 = 12
3. K = 2πr = 2 × 3.14 × 15 = 94.2 cm
D = 2r = 30 cm
Jawaban:
A:
d= K÷π = 308÷22/7 = 308×7/22 = 2.156/22 = 98
r= K÷π÷2 = 308÷22/7÷2 = 308×7/22÷2 = 49
B:
K= π×d = 3,14×24 = 75,36
r= d÷2 = 24÷2 = 12
C:
K= 2×π×r = 2×3,14×15 = 94,2
d= r×2 = 15×2 = 30
