Jawaban:
b. K = 44 Cm → d = 14cm dan r = 7cm
c. K = 132 Cm → d = 42cm dan r = 21cm
d. K = 110 Cm → d = 35cm dan r = 17,5cm
e. K = 314 Cm (π = 3,14) → d = 100cm dan r = 50cm
Soal b.
K = π x d
44cm = x d
d = 44cm x
d = 14cm
r = d : 2
r = 14cm : 2
r = 7cm
Soal c.
K = π x d
132cm = x d
d = 132cm x
d = 42cm
r = d : 2
r = 42cm : 2
r = 21cm
Soal d.
K = πd
110cm = x d
d = 110cm x
d = 35cm
r = d : 2
r = 35cm : 2
r = 17,5cm
Soal e.
K = π x d
314cm = 3,14 x d
d = 314cm : 3,14
d = 100cm
r = d : 2
r = 100cm : 2
r = 50cm
