What is the area of a circle with a diameter of 24 meters (use 3.14 for Pi)?
Zarrin [17]

The area of a circle is represented by the equation:


A=\pi r^{2}


We know that the diameter is two times the radius: d=2r


So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:


24m=2r -->r=12m


So then we can plug this radius in to the equation for the area of a circle:


A=\pi (12)^{2}


A=144\pi


We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:


A=3.14(144)


A=452.16m^{2}


Now we know that the area of this circle is 452.16 square meters.
