A 7 mm diameter circle is the equivalent of a circle with a 0.275-inch diameter.

The area of a circle with a 7-foot diameter is: 38.48 square feet.

The area of a 7-inch circle is: 38.48 square inches.

The radius is half of the diameter. So, if the radius is 7 the diameter is 14.

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

It depends on what you mean by a "7-inch circle". If, as is normally the case, it is a circle with a 7-inch diameter, then you've got your answer in the question. If, unusually, you mean a circle with a 7-inch radius, then the diameter is twice that - 14 inches. If, even more unusually, you mean a circle with a circumference of 7 inches, then the diameter is 7/pi = 2.228 inches.
