If the circumference of a circle is 62.8 inches the diameter is: 20 inches.
The diameter of a 20 foot circumference circle is about 6.366 feet. (C / Pi = diameter).
The circumference of a circle with a diameter of 20 inches is: 62.83 inches. (C = d x Pi)
62.83185/pi = 19.99999902 or about 20 units in length.
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft
Circumference of the circle is: pi*20'
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
The circumference of a circle with a diameter of 20 centimeters is: 62.83 cm (diameter x Pi = circumference).
If the circumference of a circle is 20 feet the diameter is: 6.366 feet (circumference divided by pi = diameter).
The circumference of a circle with a diameter of 20 feet is: 62.83 feet (diameter x Pi = circumference).
If the circumference of a circle is 62.8 inches the diameter is: 20 inches.
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
The diameter is 20.
The diameter will be about 6.37
If the circumference of a circle is 20 cm, the diameter will be: 6.37 cm (D = c divided by Pi).
If the diameter of a circle is 20 inches, the circumference is about 62.83 inches. (C = d x Pi).
circumference in feet = 20*pi
