Ili kukokotoa ujazo wa tanki la maji lenye umbo la silinda, tutatumia fomula ya ujazo wa silinda.

Kutoka kwenye swali, tunapewa:

Andika fomula ya ujazo wa silinda.
Fomula ya ujazo ( $V$ ) wa silinda ni:
$V = \pi r^2 h$
Tutatumia $\pi = \frac{22}{7}$ kwa hesabu hii.
Badilisha thamani za $r$ , $h$ , na $\pi$ kwenye fomula.
$V = \frac{22}{7} \times (1.4 \text{ m})^2 \times 2.1 \text{ m}$
Kokotoa $r^2$ .
$(1.4 \text{ m})^2 = 1.4 \times 1.4 \text{ m}^2 = 1.96 \text{ m}^2$
Fanya hesabu.
$V = \frac{22}{7} \times 1.96 \text{ m}^2 \times 2.1 \text{ m}$
Rahisisha kwa kugawanya 1.96 na 7:
$1.96 \div 7 = 0.28$
Sasa endelea na hesabu:
$V = 22 \times 0.28 \text{ m}^2 \times 2.1 \text{ m}$ $V = 6.16 \text{ m}^2 \times 2.1 \text{ m}$ $V = 12.936 \text{ m}^3$
Ujazo wa tanki la maji ni:
$\text{12.936 m}^3$
