Remember the circle eq'n C = pi d AlgebraicaLLY REARRGANGE d = C / pi d = 22/3.141502.... d = 7.002817496... ~ 7.0
The diameter of a circle is 56 cm. What is the circumference of the circle? Use 22/7 to approximate for pi.
Divide the area by pi. (3.14 or 22/7) Find the square root of your answer. This will be the radius. Multiply the raduis by 2.
Diameter being 22 meters, the area is 380.12 meters
A ≈ 380.13
380.1 square units.

A semicircle is half a circle, so its area is half that of a circle: radius = 1/2 diameter = 22 ÷ 2 = 11 area = 1/2πr2 = 1/2π112 ~= 190 sq in
diameter= 5m radius= diameter/2 = 5/2 =2.5m area of the circle= πr*r =22/7*2.5*2.5 =19.64....m
The circumference of a circle with a diameter of 22 is 22 times pi or approximately 69.08.
The area of a circle is pie(22/7) or (3.14) times R2 R = the radius of the circle (1/2 of the diameter)
Area of circle is pi . r.r . Area is 22/7 . 9.1 . 9.1 equalls 260.02 sq.units.
