Answer
Area of Watch: 0.8 in$^{2}$
Circumference of Watch: 3.1 in
Area of Clock: 28.3 in$^{2}$
Circumference of Clock: 18.8 in
Work Step by Step
Area of a Circle: $A$ = $\pi$$r$$^{2}$
Area of a Circle: $A$ = $\pi$$d$$^{2}$/4
Circumference of a Circle: $\pi$$d$
Circumference of a Circle: 2$\pi$$r$
Therefore:
$A$$_{watch}$ = (3.14)(1 in)$^{2}$ / 4
$A$$_{watch}$ = 0.8 in$^{2}$
$C$$_{watch}$ = (3.14)(1 in)
$C$$_{watch}$ = 3.1 in
$A$$_{clock}$ = (3.14)(3 in)$^{2}$
$A$$_{clock}$ = 28.3 in$^{2}$
$C$$_{clock}$ = 2(3.14)(3 in)
$C$$_{clock}$ = 18.8 in
