If you meant that is 7 in circumference, then divide by pi.
7/3.1416 = 2 Answer is rounded to one significant figure.
If you meant 7 in radius, then multiply by 2 to get diameter
7 X 2 = 14.
There are about 38.48 square feet in a 7' diameter circle
7/pi = diameter
The diameter of a circle is twice the radius. When the diameter is 7 metres, the radius is 3.5 metres.
The area of a circle with a 7-foot diameter is: 38.48 square feet.
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
There are about 38.48 square feet in a 7' diameter circle
diameter = 2*7 = 14mm
7/pi = diameter
The diameter of a circle is twice the radius. When the diameter is 7 metres, the radius is 3.5 metres.
The diameter would be approximately 7. In exact figures it would be 7
A circle with a diameter of 7 inches has an area of 38.48 square inches.
The area of a circle with a 7-foot diameter is: 38.48 square feet.
The circumference of a 7 feet diameter circle is: about 21.99 feet.You can easily to this calculation for other circles by multiplying the diameter by Pi (about 3.1416). The result is the circle's diameter.
The diameter is 7
circumference of a circle = pie times the diameter = 22/7 x diameter = 22/7 x 7 inches = 22 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.
