Steps to finding the area of a circle?

1. Measure the radius and multiply it by itself (square it) 2. Multiply Pi (3.14159....) with answer of step 1. That will be the area. Area of circle = Pi x radius2 Radius = Half the diameter of the circle.


What does square the circle mean?

to construct (using a compass and straight-edge) a square with the same area as a given circle using only a finite number of steps. "Squaring the circle" was an ancient problem that has been proved impossible to do.


Why can a circle not have the same area as a square?

This depends on the circle you're talking about. A theoretical circle and square most certainly could have the same area. If the circle's radius is 1, then the square's length and width would be √π. The problem here is actually in creating such a measurement in a finite number of steps. Because pi is a transcendental number, that is not possible.


How do you find the area of a circle if the circle is 8cm?

Area of a circle = pi*radius2


How do you get an area for a circle?

Area of a circle = Pi * radius2


How you get the area of circle?

What is An area of circle?

The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.


Help with math how do you get the area of a circle?

Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.


If the area of one circle is twice that of another circle what is the ratio in percent of smaller to larger circle?

If the area of one circle is twice that of another, the ratio of the area of the smaller circle to the larger circle is 1:2. To express this as a percentage, the area of the smaller circle is 50% of the area of the larger circle. Thus, the ratio in percent of the smaller circle to the larger circle is 50%.
