A)r=6cm d=2x6=12cm t = 8cm L s = k lingkaran x tnggi = 3,14 x 12 x 8 = 301,44 cm2 b) d=8cm r = d : 2 = 8 : 2 = 4 cm t = 10 cm L s = 3,14 x 8 x 10 = 251,2 cm2 c) r = 7 cm d = 2 x 7 = 14 cm L s = 22/7 x 14 x t 440 cm2 = 44t t = 440 : 44 = 10 cm d) L s = 22/7 x d x 8 352 = 176d/7 176d = 2464 d=2464/176=14cm r=d:2=14:2=7 cm
d=2x6=12cm
t = 8cm
L s = k lingkaran x tnggi
= 3,14 x 12 x 8 = 301,44 cm2
b) d=8cm
r = d : 2 = 8 : 2 = 4 cm
t = 10 cm
L s = 3,14 x 8 x 10 = 251,2 cm2
c) r = 7 cm
d = 2 x 7 = 14 cm
L s = 22/7 x 14 x t
440 cm2 = 44t
t = 440 : 44 = 10 cm
d) L s = 22/7 x d x 8
352 = 176d/7
176d = 2464
d=2464/176=14cm
r=d:2=14:2=7 cm
