1. The area of a circle is
[tex]a = \pi {r}^{2} [/tex]
[tex]\pi = 3.14 \\ r = \frac{3.4}{2} = 1.7[/tex]
[tex]a = (3.14) {(1.7)}^{2} \\ = 9.0746[/tex]
The area is 9.07 cm^2.
2. The volume of a cube is
[tex]v = {s}^{3} [/tex]
[tex]s = 4.5[/tex]
[tex]v = {(4.5)}^{3} \\ = 91.125[/tex]
The volume is 91.125 m^3
