The line from the centre of the circle to any point on its circumference
Yes.
The formula is pi (3.14) x radius x radius 3.14 x 12 x 12 = 446.4
The area of a cirle is: PI * r2 Where "r" is the radius, and PI is approximately 3.14. Hint: A radius is half of the diameter.
The radius of a circle is always PRECISELY one half its diameter.

the radius of a cirle is what percent of the diameter
Yes.
pi*radius squared
The area of a circle of radius r is pi*r*r
circumference of a circle = 2*pi*radius or pi*diameter
The formula is pi (3.14) x radius x radius 3.14 x 12 x 12 = 446.4

The radius of a circle is half of its diameter. Since the diameter of the circle is 24 inches, the radius would be 24 inches divided by 2, which equals 12 inches. Therefore, the radius of a 24-inch circle is 12 inches.
To find the area of a cirle you multiple pi (3.14) by the radius squared, so you would have to find 3.14 times 4, which is 15.7.
circumference of a cirle = 2*pi*r pi=3.14 r=radius
