Jawab:
1. 616 cm3
2. 2.072,4 cm3
3. 1.381,6 cm3
Penyelesaian:
1. LP = 2 x π x r ( r + t )
= 2 x 22/7 x 7 ( 7+10)
= 2 x 22/7 x 7 x 17
= 2 x 308
= 616 cm3
2. LP = 2 x π x r ( r + t )
= 2 x 3,14 x 15 ( 15 + 7 )
= 2 x 1.036,2
= 2.072,4 cm3
3. LP = 2 x π x r ( r + t )
= 2 x 3,14 x 10 ( 10 + 12 )
= 2 x 690,8
= 1.381,6 cm3
