By definition pi is the ratio between the circumference and the diameter
pi=C/D so C=pi*D and C=pi*40=125.6 (if pi=3.14)
The circumference of a circle, if the diameter is 40 inches, is about 125.7 inches. (C = d x Pi).
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
Circumference= PI x Diameter = 3.14 x 40 feet = 125.6 feet
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
127.324 square units correct to 3 decimal places
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
The circumference of a circle, if the diameter is 40 inches, is about 125.7 inches. (C = d x Pi).
The circumference of a 12-foot-diameter circle is 37.7 feet.
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
Circumference= PI x Diameter = 3.14 x 40 feet = 125.6 feet
The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is 40 feet. So, the circumference would be C = π(40) = 40π feet, or approximately 125.66 feet.
Circumference of any circle = 2*pi*radius or diameter*pi
It is impossible to answer the question because the circumference cannot be 40 degrees.
About 40 feet. Circumference = 3.14 x diameter
125.66 mm
circumference? 40 pi ft.
Circumference = Pi x d: 40 = 3.14 x 40 = 125.6 feet
