the formula for the circumference of the circle is:
[tex]C=2\pi r[/tex]
where:
C=circumference
π=the constant pi
2r = diameter = 14
Then:
[tex]C=14\pi=43.98[/tex]
Moreover, the formula for the area of the circle is:
[tex]A=\pi r^2[/tex]
where
A=area
r=radius = 1/2 * diameter = 7
Then:
[tex]A=7^2\pi=\: 153.94[/tex]
From the above
circumference, C = 43.98
Area, A = 153.94
