Jawaban:
1. L = ¾ x π x r x r
=¾ x 3,14 x 20 x 20
=¾ x 3,14 x 400
= ¾ x 1256
= 942
K = ¾ x π x 2 x r + 20 + 20
= ¾ x 3,14 x 2 x 20 + 20 + 20
= ¾ x 3,14 x 40 + 20 + 20
= ¾ x 125,60 + 20 + 20
= 94,2 + 20 + 20
= 114,2 + 20
= 134,2 m
2. L = π x r x r
= 3,14 x 50 x 50
= 3,14 x 1000
= 3140,00
K = π x 2 x r
= 3,14 x 2 x 50
= 3,14 x 100
= 314
