NA.	UMBO/MCHORO	KANUNI
1.	Mche mstatili.	Eneo la mche mstatili. $Eneo = (ur. \times up. \times 2) + (ur. \times h \times 2) + (up. \times h \times 2)$ $ur. = urefu, \;\; up. = upana, \;\; h = kimo$
2.	Mche duara ulio wazi pande zote.	Eneo la mche duara ulio wazi pande zote. $Eneo = 2 \pi rh \;\; AU \;\; Eneo = \pi dh$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
3.	Mche duara uliozibwa upande mmoja.	Eneo la mche duara uliozibwa upande mmoja. $Eneo = 2 \pi rh + \pi r^2 \;\; AU \;\; Eneo = \pi dh + \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
4.	Mche duara uliozibwa pande zote.	Eneo la mche duara uliozibwa pande zote. $Eneo = 2 \pi rh + 2 \pi r^2 \;\; AU \;\; Eneo = \pi dh + 2 \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
5.	Mche pembetatu.	Eneo la mche pembetatu. $Eneo = [E \Delta (ABE) \times 2 ]+ [E(ABCF) \times 2] + [E(AEDF) \times 2] + [E(EBCDE)\times 2]$
5.	Mche mraba.	Eneo la mche mraba. $Eneo = (Up. \times Up. \times 6)$ $Up. = upande$
