Question

Tolong jawab ya pliss

Answer 1

1) L = P x L
= 80 x 60
= 4800

2) L = sisi x sisi
2500 = sisi pangkat 2
sisi = akar 2500
sisi = 50 cm

3) L = alas x tinggi : 2
= 60 x 40 : 2
= 1200

nomor 4,5,6,7,8 maaf aku udh lupa rumusnya hehe

9) L = pi x r kuadrat
= 22/7 x 21 kuadrat
= 22/7 x 441
= 1386

10) L = pi x r kuadrat atau L = pi x diameter

1,54 dm kuadrat = 154 cm kuadrat

L = pi x d
154 = 22/7 x d
d = 1



semoga membantu
