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))

What is the circumference of a pool that has a diameter of 22 feet?
Circumference of a circle = (pi) x (diameter)C = (22) x (pi) = 69.115 feet (rounded)
If the diameter of a circle is 7 inches what is the circumference?
circumference of a circle = pie times the diameter = 22/7 x diameter = 22/7 x 7 inches = 22 inches
What is the approximate area of a semicircle with a diameter of 22 inches?
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

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.
How many square inches in a 3 inch diameter circle?
The area of a circle is calculated using the formula A = πr^2, where r is the radius (half the diameter). In this case, the radius is 1.5 inches (half of 3 inches). So, the area of the circle is A = π(1.5)^2 = 7.07 square inches.
If the radius of a circle is 15 inches what is the diameter?
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
