36cm squared
Answer:
If a square is nine INCHES on a side, its area will be measured in square inches. The formula for area is side times side, 9"X9"= 81 square inches.
If the square is made up of nine one inch squares, that would be 3"x3"= 9 square inches.
The area of a 3-inch square is: 9 square inches.
9 x 13 = 117 square inches
You can't. Square inch is a measure of area and inch is a measure of length.
Surface area of a 3 inch square is 54 inches.
If you are talking about 9 and 12 inch diameter, then divide both by 2 to get the radius. The area of a circle is pi (3.1415 is good for most calculations) multiplied by the square of the radius. So for the 12 inch circle, the radius is 6. The square of the radius is 36, and multiplying this by pi gives approximately 113.1 square inches. Now the 9 inch circle has a radius of 9/2 or 4.5. Squaring this we get 20.25, which multiplied by pi is approximately 63.6 square inches. If 9 and 12 were already the radius in the problem, just don't divide by 2 since you already have the radius.
The area of a 3-inch square is: 9 square inches.
Area = pi*9*9 square inches
9 x 13 = 117 square inches
Area of rectangle: 9 times 11 = 99 square inches
3.897 square inches.
The area of one 4 inch by 9 inch brick is 36 square inches.The area in square inches of 200 square feet of wall is 28800 square inches (200 x 12 x 12).The number of 36 square inch bricks to cover an area of 28800 square inches is 800 (28800/36).
A 6 x 9 inch oval is a 3 inch x 3 inch square with a semicircle of 3 inch radius at each end. The total area is, therefore, 9 + 9*pi = 27.3 sq inches. Note that an oval is NOT an ellipse.
1 square inch
If square has a 28-inch perimeter its area is: 49 square inches.
A circle with a diameter of 14 feet 9 inches has an area of: 170.87 square feet.
An area of 1 square inch!
A square inch does not have a specific number of inches in it because a square inch is a unit of area, not length. It represents the area of a square with sides that are each 1 inch long.
