Answer: 2 A=pi x radius squares so 12.56/3.14159 is the radius squared, Now to find the radius take the square root of that. So we have r squared is 3.9997 or very close to 4 so the radius is very close to 2. We can say it is two in this case we say it is two since we are only dealing with hundreds and 3.9997 rounds to 4

The area of a circle is 153.86cm².find the radius of the circle

When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.

A circle with a radius of 4 cm has an area of 50.27 square cm.

The area of a circle with a radius of 7 cm is: 153.9 cm2

The area of any circle is (pi) x (radius)2 .The area of half the circle is just half of that number.
