the area of a circle found using pi r square. the radius is half the diameter therefore the radius is 2.8 = 22/7x 2.8^2=24.64
22
The diameter of a 22 circumference circle is: 7
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)
Well, isn't that just a happy little question! To find the diameter of the circle, you simply need to multiply the radius by 2. Since the radius is 22 millimeters, the diameter would be 44 millimeters. And if you want to convert that to centimeters, you can divide by 10 because there are 10 millimeters in a centimeter. So, the diameter of the circle would be 4.4 centimeters. Happy calculating!
