If the diameter of a circle is 2 inches the circumference is: about 6.283 inches (c = d x pi).
A circle with a radius of 16 inches (32/2) has a circumference of 100.53 inches.
Circumference of the circle: 2*pi*radius or diameter*pi depending on what 8 inches represents
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
11.5/pi, almost exactly 3 and 2/3 inches
Oh, dude, you're hitting me with the math questions, huh? Alright, alright. So, the circumference of a circle is calculated by multiplying its diameter by pi (π). Since the diameter of a 1.25-inch circle is also 1.25 inches, you just gotta do 1.25 x π. So, the circumference would be approximately 3.93 inches. Easy peasy, right?
A circle with a radius of 16 inches (32/2) has a circumference of 100.53 inches.
Diameter of a circle = 2*radius Diameter of a circle = circumference/pi
A circle with a radius (d/2) of 39.25 inches has a circumference of 246.6 inches.
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of the circle: 4 times pi in inches
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches
If its diameter is 10 inches then its circumference is: diameter*pi If its radius is 10 inches then its circumference is: 2*pi*10
Circumference of a circle = pi*diameter or 2*pi*radius Circumference = 11.62389282 inches
Circumference = pi*d = 169.65 inches (to 2 dp)
Circumference = 2 x pi x radius = pi x diameter where pi = 3.1416 Diameter = circumference / pi = 36/3.1416 = 11.46
The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.
