tolong dijawab ya kakkkkkkkk

1) V = La × t
= π × r² × t
= 3,14 × 15 × 15 × 30
= 21.195 m³

2) L = a × t
240 = 16 × t
t = 240 ÷ 16
t = 15 cm

3) V = π × r² × t
= 22/7 × 70 × 70 × 26
= 400.400 cm³

4) L = ½ × d1 × d2
= ½ × 17 × 21
= 178,5 m²

5) d = 14 m
r = 7 m
L1 = π × r²
= 22/7 × 7 × 7
= 154 m²

L2 = π × r²
= 3,14 × 3 × 3
= 28,26 m²

Luas daerah
= 154 - 28,26
= 125,74 m²
