MAPEL = MATEMATIKAKELAS = 9
BAB = BANGUN RUANG
diketahui =
diameter = 12cm maka r = 6cm
tinggi = 8cm
ditanya =
luas selimut kerucut??
untuk menentukan garis pelukis kita gunakan teori phytagoras yg maka
s = √r² + t²
s = √6² + 8²
s = √36 + 64
s = √100
s = 10
luas selimut kerucut = πrs
= 3,14 × 6 × 10
= 188,4 cm²
semoga membantu
