kell = 2.pi.r
44 = 2 . . r
44 = . r
7 = r
Ls = pi . r . s
= . 7 . 25 -->> ( mencari s nya dari tripel 7,24,25)
= 22 . 25
= 550 cm² ( 1 topi )
100 topi = 55000 cm²
**maaf kalau salah
2 x phi x r = 44
2 x 22/7 x r = 44
44/7 x r = 44
r = 44 x 7/44
r = 7
jari-jari = 7
maka sisi miring = 25
luas selimut = phi x r x s
= 22/7 x 7 x 25
= 22 x 25
= 550
luas selruhnya
100 x 550 = 55.000cm²
= 550m²
