Question

Dik r kerucut=6cm
s. =10cm
dit:a.luas selimut
b.luas kerucut

Answer 1

A. Luas selimut kerucut
= phi x r x s
= 3,14 x 6 x 10
= 3,14 x 60
= 188,4 cm²

b. Luas kerucut
= phi x r² + phi x r x s
= 3,14 x 6 x 6 + 3,14 x 6 x 10
= 3,14 x 36 + 3,14 x 60
= 113,04 + 188,4
= 301,44 cm²
maaf kalo salah
