Area of a Circle
Given a circle of radius r, its area is calculated as follows:
[tex]A=\pi\cdot r^2[/tex]We are given the diameter of a circle of d = 14 m. The radius of a circle is half the diameter, thus:
r = d/2 = 14 m / 2 = 7 m
Applying the formula:
[tex]A=\pi\cdot7^2=49\pi m^2[/tex]Substituting π for the approximate value of 22/7:
[tex]A=49\cdot\frac{22}{7}m^2=154m^2[/tex]Answer: 154 m2
