How many Square inches in a 14 inch circle?

I assume that a 14 inch circle is a circle 14 ionches in diameter. Use the formula Area = Pi x radius of the circle X radius of the circle The radius is half the diameter. Pi is 3.14159 (appx) So the area = 3.14159 X 7 X 7 = 153.937 square inches. Or approximately 154 square inches

If the diameter of a circle is sixteen feet what is the value in inches?

The value of a circle could mean many things. Assuming the question is asking for the diameter of a sixteen-foot-diameter circle in inches, the diameter of the circle would be 192 inches. ---- One foot equals twelve inches [ 1 ft. = 12 in. ] Sixteen times twelve equals one-hundred ninety-two [ 16 * 12 = 192 ] Sixteen feet equals one-hundred ninety-two inches [ 16 ft. = 192 in. ]


A circle is cut out of a piece of plywood that is 10 inches square The scraps are then thrown away How many square inches of plywood are thrown away?

The area of the square was 100 sq in (10 x 10). Assuming the circle was cut out of the square form edge to edge, the area of the 10 inch diameter circle is found as follows: A = Pi x R² where Pi is 3.1416 and R² is the radius multiplied by itself (the radius is one half of the diameter). Using the formula: A = 3.1416 x (5 x 5) = 3.1416 x 25 = 78.54 sq in. Subtract the area of the circle from the area of the square to find how much material was thrown away. (100 - 78.54 = 21.46 sq in)
