A circle 14 inches in diameter has a radius of 7 inches, and a circle having a radius of 7 inches has a diameter of 14 inches.
7/pi = diameter
The area of a circle with a 7-foot diameter is: 38.48 square feet.
A 7 mm diameter circle is the equivalent of a circle with a 0.275-inch diameter.
14 inches.
A circle with a diameter of 7 inches has an area of 38.48 square inches.
A circle with a 7 inch diameter has an area of 38.48451.
Diameter = 14 inches Radius = 14/2 = 7 inches Area of circle = pi x r x r = 3.1415 x 7 x 7 = 153.9335 square inches
A circle 14 inches in diameter has a radius of 7 inches, and a circle having a radius of 7 inches has a diameter of 14 inches.
Diameter will be 7/pi inches
circumference of a circle = pie times the diameter = 22/7 x diameter = 22/7 x 7 inches = 22 inches
The circumference of a circle if the diameter is 7 inches and Pi is 3.14 is: about 21.98 inches.
It is: pi*3.5 squared = 38.485 square inches rounded
7/pi = diameter
area = 3.14 x 7 x 7 / 4 = 38.465 square inches
The diameter is approximately 7 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.
