The diameter of a circle is 14 m. What is the area of the circle? Use for 22/7 for π 616 m244 m2154 m21,078 m2

Answer 1

Area of a Circle

Given a circle of radius r, its area is calculated as follows:

$A=\pi\cdot r^2$

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:

$A=\pi\cdot7^2=49\pi m^2$

Substituting π for the approximate value of 22/7:

$A=49\cdot\frac{22}{7}m^2=154m^2$

Answer: 154 m2
