no it is different.
It is: 7/pi inches
C = 44 inches
Circumference = pi*diameter = 21.99 inches, approx.
7 foot circumference X 12 inches/foot = 84 inches in circumference
Circumference = 7*pi 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.
Oh, dude, the circumference of a circle is like the circle's waistline, you know? So, for a 7-inch circle, you just gotta use the formula C = 2πr, where r is the radius (half the diameter). In this case, the radius is 3.5 inches, so the circumference is 2 x π x 3.5, which is around 21.99 inches. But hey, who's really measuring a circle's waist, am I right?
The circumference is 21.99 inches.
Circumference = 7*pi which is about 22 inches
Of course. If the length of each side is 7/4 inch (which is the same as 1.75 inches), then the perimeter is 7 inches.
The circumference of a circle if the diameter is 7 inches and Pi is 3.14 is: about 21.98 inches.
7 feet 5 inches = 89 inches circumference = 89*pi inches
