if a circle has a diameter of 4 meters what is the area of the circle?
Using the formula: \(\pi r^2\)
Which is, 3.14 x 2^2 (radius is half of diameter)
Which equals 12.56.
The area of the circle is 12.56
This refers to the occupied region of a circle in a two-dimensional plane.
Hence, we know that the formula is A=πr2
\pi*r^2
and the value of \pi is 3.14
Hence, 3.14 x 2^2
= 12.56
