Circumference = pi*38 = 119.3805208 or about 119.381 inches
Circumference of a circle = π x DC = 3.14159 x 38C = 119.38 inches
It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
Circumference = 2*38*pi feet
if the diameter is in feet then multiply the diameter by pi 38 x 3.14159 = 119.38042 square feet if the diameter is in inches then dividethe inches by 12 then multiply the diameter by pi 38 ÷ 12 = 3.16666 x by 3.14159 = 9.94835 square feet
Circumference of the circle: 38*pi in miles
The diameter is about 12.1
The circumference of an 8-foot circle is: 25.13 feet.
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
Circumference = pi*38 = 119.3805208 or about 119.381 inches
That depends on what is meant by 38 mi but the circumference of any circle is 2*pi*radius or diameter*pi
Circumference = 2*pi*radius or diameter*pi
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
12 inch diameter(also 6 inch radius).
12 inch diameter(also 6 inch radius).
Diameter = Circumference/pi = 38/pi = 12.1 inches
If the 19' is referring to the circumference of a circle then the diameter is approx. 6.0479'. 19÷3.1416=approx. 6.0479 If the 19' is referring to the radius, (from center of the circle to the outside edge), then the answer is 38'. diameter= radius X 2. 19X2=38
