Answer:
82.6cm2
Step-by-step explanation:
[tex]\pi {r}^{2} + \pi {r}^{2} + 2 \pi \: r h[/tex]
[tex]\pi = \frac{22}{7} [/tex]
radius =2cm
height=8cm
[tex]( \frac{22}{7} \times 2 \times 2 )+ ( \frac{22}{7} \times 2 \times 2) + (2 \times \frac{22}{7} \times 2 \times 8)[/tex]
Multiplying the numerators and The whole numbers, we have
[tex] \frac{88}{7} + \frac{88}{7} + \frac{402}{7} [/tex]
Since the denominators of the fractions are the same, we add the numerators.
[tex] \frac{88 + 88 + 402}{7} = \frac{578}{7} \\ which \: becomes \\ [/tex]
[tex] 82.57{cm}^{2} = 82.6 {cm}^{2} [/tex]
