The general eq'n for a circles area is
A = pi r^(2)
Hence
With a diamter of 22 inches . the radius(r) is half the diameter at 11 inches.
Substituting
A = pi 11^(2)
A = 121 pi
Using pi = 3.14
Hence
A = 121 X 3.14
A = 379.94 sq.ins. (NOT ins^(2))

Circumference of a circle if diameter is 22 cm?
The circumference of a circle is always its diameter multiplied by pi. Therefore, the circumference of a circle with diameter 22 cm is:П*22 = 69.12answer rounded to the nearest hundredth
What is diameter of 28 inch circumference?
To find the diameter of a circle with a circumference of 28 inches, we can use the formula C = πd, where C is the circumference and d is the diameter. Given that C = 28 inches, we can rearrange the formula to solve for d: d = C / π. Therefore, the diameter of a circle with a circumference of 28 inches is approximately 8.91 inches.

How do you find the area of a semi circle or quarter circle when pi is twenty two sevenths and please include an example for both semi circle AND quarter circle?
The area of a circle is pi*r2, where r is the radius. In this case, 22/7 will be used for pi. Area of a semicircle: A semicircle is half of a circle, so the area will be half of a circle: A = (1/2)*pi*r2 Example: Find the area of a semicircle with a radius of 10 meters. A = (1/2)*(22/7)*(10)2 = (1/2)*(22/7)*(100) = 1100/7 or about 157.14 square meters Area of a quarter circle: A quarter circle is a forth of a circle, so the area will be A = (1/4)*(pi)*r2 Example: Find the area of a quarter circle with a diameter of 4 inches: (Notice that the diameter is given, so the radius in this case is 2 inches:) A = (1/2)*(22/7)*(22) = (1/2)*(22/7)*4 = 44/7 or about 6.286 square inches.
If the radius of a circle is 15 inches what is the diameter?

How many square inches in a 3 inch diameter circle?
When you say "a 20 inch circle", I'm going to assume you mean the distanceall the way across it, through the center ... that is, the circle's "diameter".The area of a circle is (pi) x (Radius)2 = (pi) x (100) = 314.159 square inches (rounded)
