To calculate the square inchec, multiply one side by the other. For example, in a 3 x 9 inch square, multiply 3 x 9, which gives you 27 square inches.
3 inches
The area of a 3-inch diameter circle is about 7.068 square inches.
12 square inches.
The area of a 3-inch square is: 9 square inches.
Surface area of a 3 inch square is 54 inches.
Area = pi*102 = 314.159 square inches to 3 decimal places
Area = pi*42 = 50.265 square inches to 3 decimal places
(13 ft 3 inches) x (13 ft 9 inches) is approximately 16.93 square meters.
To find the cross-sectional area of a 6-inch pipe, you can use the formula for the area of a circle, A = πr². The radius (r) of a 6-inch diameter pipe is 3 inches. Therefore, the area is A = π(3 inches)² ≈ 28.27 square inches.
12 inches
A three inch wide square has the dimensions of 3x3. (9 square inches)
The answer depends on the units used for 3 X 8. It should, for example, be obvious that the number of square inches in a 3 inch x 8 inch shape will be different to the number of square inches in a 3 foot x 8 ft area.
