Verified answer
MAPEL = MATEMATIKAKELAS = 9
BAB = BRSL
diketahui =
diameter = 48 cm
jari jari = ½ × 48 = 24cm
tinggi = 10cm
ditanya =
luas luar topi = luas selimut kerucut ?
s = √t² + r²
s = √10² + 24²
s = √100 + 576
s = √676
s = 26
luas selimut kerucut = πrs
= 3,14 × 24 × 26
= 3,14 × 624
= 1959,36 cm²
semoga membantu
