Circumference of a circle with radius 14 cm

Formula for circumference
$C = 2\pi r$
Substitute $r = 14~\mathrm{cm}$
$C = 2\pi \times 14~\mathrm{cm}$
Simplify
$C = 28\pi~\mathrm{cm}$
28\pi~cm

Circumference of a circle with diameter 49 cm
Formula for circumference
$C = \pi d$
Substitute $d = 49~\mathrm{cm}$
$C = \pi \times 49~\mathrm{cm}$
Simplify
$C = 49\pi~\mathrm{cm}$
49\pi~cm

Area of a circle with radius 12 cm
Formula for area
$A = \pi r^{2}$
Substitute $r = 12~\mathrm{cm}$
$A = \pi (12~\mathrm{cm})^{2}$
Simplify
$A = \pi \times 144~\mathrm{cm}^{2}$ $A = 144\pi~\mathrm{cm}^{2}$
144\pi~cm^{2}
