Question

Tolong jawab no 3,4,5. Secepatnya....

Answer 1

3)a. c^2 = 12^2 + 5^2
c^2 = 144 + 25
c^2 = 169
c = 13 cm

b. 2L.alas + L. sisi tegak
2(1/2 × 12 × 5) + ((12 + 5 + 13) × 20)
60 + 600 = 660 cm^2

4)a. r^2 × t = V
r^2 × 12 = 1296
r^2 = 1296/12
r^2 = 108 cm
r = √108 cm = 6√3 cm

b. jawabannya nggak nyambung, 216 + 48√108 cm^2

5) 1 m = 10 dm
0,5 m = 5 dm
2/3L = 200
L = 300lt
10 × 5 × t = 300
50t = 300
t = 6 dm = 0,6m
