Dit LP dan V
Jawaban V=
Jawaban Lp=
Jawaban:
Lp =785cm²
V = 1.570cm³
Caranya:
Diketahui:
d = 10
t = 20
Ditanya:
Lp = ?
V = ?
Jawab:
r = d ÷ 2
r = 10 ÷ 2
r = 5
~~~~~~~~~
V = π × r × r × t
V = 3,14 × 5 × 5 × 20
V = 1.570
~~~~~~~~~~
Lp = 2 × π × r × ( r + t )
Lp = 2 × 3,14 × 5 × ( 5 + 20)
Lp = 2 × 3,14 × 5 × 25
Lp = 785cm²
