Question

Kak tolong bantu aku ya matematika no. 1 - 6 pake caranya

makasih kakak

Answer 1

1. 14=1/4×m×d×d
=1/4×22/7×14×14 (14coret sama 7 hasil 2)
=44×14/4(4 coret dengan 44 hasil 11)
=11×14
=154

2. (m×r2)×t
=22/7×14×14×20(7 coret dengan 14 hasil 2)
=22×2×14×20
=44×14×20
=616×20
=12,320

3. L1=p×l
=9×19 cm
=171 cm
L2=p×l
=(9-4)×(38-19)
=5×19 cm
=95 cm
L=L1+L2
=171+95
=266


4. =(A×T)/2×t
=(8×10)/2×20
=80/2×20
=1600%2
=800

semoga membantu
