Radius of circle: 157/2pi = 25 m rounded
Radius = 22/2pi m
the diameter of a circle with the radius of 9m is 18m
Perimeter of rectangle: 2*(7+6) = 26 m
The formula for an area of a circle is the greek symbol "pi" times the radius squared. A = π * r2 r = radius π = 3.14 Now, your radius is given to you in millimeters. Generally answers are given in meters. 7 mm (millimeters) is equal to .007 m (meters).

Using 3.14 as Pi the area of circle is: 153.86
The radius of a circle with circumference of 63 m is 10.03 m
The circumference of a circle with a radius of 3 m is: 18.85 m.
The radius of a circle with a circumference of 110 m is: 17.507 m
A circle with a radius of 10 m has a circumference of 62.83 m.
Radius of circle: 157/2pi = 25 m rounded
Area of a circle is = Pi * Radius Squared. Depending how accurate you want to be you might need a calculator for Pi to more places but using Pi = 3.14 3.14 * 7 * 7 = 153.86 you should supply some units. If the 7 was in m this answer is in m squared. Circumference is generally = 2 * Pi * Radius 2 * 3.14 * 7 = 43.96 again if the 7 is in meters then the answer is in m.
Radius = 22/2pi m
Perimeter = 7+7+12+12 = 38 m
Assuming you mean the radius, which is half of the diameter: 4.56 m ÷ 2 = 2.28 m
the diameter of a circle with the radius of 9m is 18m
