Question

No 5 ada yang tau gak jawabannya..?
tolong dijawab ya
klo bsa pke cara

Answer 1

2009,6 = πr²t
2009,6 = 3,14 r² 10
2009,6 = 31,4 r²
2009,6 : 31,4 = r²
64 = r²
8 = r

d= 2r
d = 2.8
d = 16 cm

Answer 2

V = la x t
2009,6 = phi x r x r x 10
2009,6 : 10 = 3,14 x r x r
r x r = 200,96 : 3,14
r x r = 64
r = akar 64
r = 8
d = 2r = 2 x 8
   = 16,yang C
