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 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.

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
use the circumference formula of a circle circumference of a circle=2*pi*r pi=22/7 r-radius of a cirle Now the answer for the problem is 11.69
