kak tolong jam 6 di kumpul soal nya difoto ya kaks
• Bangun Datar
[tex]{\boxed{\colorbox{lightblue}{ \tt{ \: Penyelesaian : \: }}}}[/tex]
K = 3/42πr
K = 3/4 × 2 × 22/7 × 3,5
K = 3/4 × 2 × 22 × 0,5
K = 3/4 × 2 × 11
K = 3/4 × 22
K = 16,5 cm
Jawaban:
[tex]luas \: = \pi {r}^{2} \\ luas \: \frac{3}{4} lingkaran \: = \frac{3}{4} \times \pi \times {r}^{2} \\ = \frac{3}{4} \times \frac{22}{7} \times {3.5}^{2} \\ = 28.875 \: cm^{2} [/tex]
