Question

Tolong dijawab beserta caranya ya:) terima kasih:)​

Answer 1

R=20/2=10
s=√10^2+24^2=√100+576=√676=26
luas selimut=πxrxs=3,14x10x26=816,4
1 m^2=10.000cm^2
banyak topi=10.000/816,4=12,24

Answer 2

cari s
s = √10² + 24²
s = √100+576
s = √676
s = 26cm

luas Kerucut
= πrs
= 3,14 x 10 x 26
= 816,4

luas karton 1m² = 10000cm²
banyak topi = 10000/816,4 = 12 topi
