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
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π 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.
The area of a 3-inch square is: 9 square inches.
Area = pi*9*9 square inches
9 x 13 = 117 square inches
The area of a sheet of paper can be calculated by multiplying its length by its width. For a 9-inch by 12-inch sheet, the area is 9 inches × 12 inches, which equals 108 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.
A 9-inch round pan has a surface area of about 63.6 square inches, while a 9x13 inch pan has a surface area of 117 square inches. To determine how many 9-inch round pans equal a 9x13 pan, you divide the area of the 9x13 pan by the area of the 9-inch round pan. This means approximately 1.84 (or 2) 9-inch round pans are needed to equal the volume of a 9x13 pan.
A 2 square foot area is equivalent to 288 square inches (since 1 square foot equals 144 square inches). Each 3 inch by 3 inch tile covers 9 square inches. Therefore, to find the number of tiles that can fit, divide the total area by the area of one tile: 288 square inches ÷ 9 square inches per tile = 32 tiles. So, 32 tiles can fit in a 2 square foot area.
If square has a 28-inch perimeter its area is: 49 square inches.
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.
