Are you referring to the circle's diameter or its cicumference? If you mean diameter then the radius is 50/2 = 25 feet If you mean circumference then the radius is 50/(2*pi) = 7.957747155 or about 8 feet
A circle with a radius of 50 units has a circumference of 314.16 units.
50 percent of diameter of a circle is the radius.
The radius is 7.96
If the diameter of a circle is 50 mm, what is the radius?
Radius is half the diameter, so a radius of 50 feet the diameter will be 100 feet.
To find the area of a circle you must square the radius. In this case the radius is 50 so 50 squared is 2500. 2500 times pi is about 7, 853.98163
The radius will be 7.96 yards.
Area = pi*r2 where r = radius = 25 feet. So area = 1963.5 sq feet
Assuming that a 100 ft circle is one with a diameter of 100 ft (ie radius of 50 feet), area = pi*502 = 1963.5 sq feet
It is 50 % since a radius is half of diameter
r = 3.9894
