Question

Plis jawab ya bantu aku

Answer 1

1. 10 x 16:2=....
3. (8 x 6)+(5 x4)=...
4. 14 x 14-1/2 x 22/7 x 7²=...
5. (7 x16 :2)+ 1/2 x 22/7 x7/2 x7/2=...

Answer 2

1. L = = = 80 cm²
2. L1 = π x r x r
= x 7 x 7
= 154 x = 38,5 x 3 = 115,5 cm²
L2 = s x s
= 7 x 7
= 49 cm²
L3 = = 52,5
= 115,5 + 49 + 52,5
= 217 cm²
3. L1 = p x l = 8 x 6 = 48 cm²
L2 = a x t = 5 x 4 = 20 cm²
= 48 + 20
= 68 cm²
4. Ls = s x s = 14 x 14 = 196 cm²
Ll = π x r x r
= x 14 x 14 = 44 x 14 = = 308 cm²
= 308 - 196
= 112 cm²
5. L1 = = 56 cm²
L2 = π x r x r
= x 7 x 7
= = 38,5
= 56 - 38,5
= 17,5 cm²

maaf kalau salah. semoga membantu
