Nusu kipenyo cha mche duara unaweza kupatikana kwa kugawanya ujazo wa mche duara kwa eneo la uso wa mduara.
Ujazo wa mche duara = 1.54 L
Kimo cha mche duara = 10 cm
n = 3.14
Ujazo wa mche duara = n * (r^2) * h
1.54 = 3.14 * (r^2) * 10
1.54 = 31.4 * (r^2)
r^2 = 1.54 / 31.4
r^2 = 0.04905
r = √0.04905
r ≈ 0.2217 cm
Hivyo, nusu kipenyo cha mche duara huu ni 0.2217 cm.

Hatua ya 1: Pata kiasi cha mche duara.
V = (4/3)πr³
V = 1.54 lita
Hatua ya 2: Badilisha lita hadi sentimita za ujazo (cm³).
1 lita = 1000 cm³
V = 1.54 - 1000 = 1540 cm³
Hatua ya 3: Tumia formula ya ujazo wa mche duara kupata jaribio (r).
1540 = (4/3)πr³
Hatua ya 4: Tatua kwa r.
r³ = 1540 - 3 / (4π)
r³ = 367.28
r = ³√367.28
r = 7.23 cm
Hatua ya 5: Pata nusu kipenyo (r/2).
r/2 = 7.23 / 2
Hatua ya 6: Jibu.
Nusu kipenyo wa mche duara ni
3.62 cm
