Jawaban:
B
Penjelasan dengan langkah-langkah:
karena 14 x 3=504vm²
dan 50 x 2=100
5) C. 942 cm²
6) A. 350 cm²
5) L = π × r × r × ¾
= 3,14 × 20 × 20 × ¾
= 31,4 × 2 × 15
= 942 cm²
6) L.⚪ = π × r × r × ¼
= 22/7 × 14 × 14 × ¼
= (22×14)/2
= 308/2
= 154 cm²
L.⬜ = s × s
= 14 × 14
= 196 cm²
L.gbng = 154 + 196
= 350 cm²
