What is the area of 4 cm?
The area of a square is equal from side to side. If the side of the square is 4 inches, then the area of the square from side to side, which is 4 x 4 equals 16 square inches.
How do you solve the perimeter?
To calculate the circumference of a circle, multiply the diameter of the circle by π (pi). The circumference can also be calculated by multiplying 2 × radius by pi (π = 3.14).

What is the diameter of radius 4?
For example, if the circumference is 12.56, you would divide 12.56 by 3.14159 to get 4, which is the diameter of the circle. Use the diameter to find the radius by dividing the diameter by 2. For example, if the diameter is 4, the radius would be 2.
How do you calculate the diameter?
If you know the radius of the circle, double it to get the diameter. The radius is the distance between the center of the circle and its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2 or 8 cm. Once you know the circumference of the circle, divide it by π to get the diameter.
