circumference of a circle = 2*pi*radius or diameter*pi
Radius = Diameter/2 Diameter = 2* Radius
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
A radius is half of a diameter. Example Diameter:4 Radius:2
The diameter of a circle is twice its radius.
A 100 mile radius from Orem is 100 miles.
The radius of a circle is 1/2 of its diameter
The diameter is 31 times 2 = 62 miles
100. The radius is 1/2 of the diameter.
Radius is half the diameter, so a radius of 50 feet the diameter will be 100 feet.
Its diameter will be: 2*100 = 200 miles
The diameter of a 100-unit circumference circle is: 31.83 units.
That depends whether the "10-mile circle" refers to the circle's radius, its diameter, or its circumference. Assuming it is the diameter, divide it by 2 (to get the radius), then use the formula: area = pi x radius2.
It is 100 units.

i think it is a 100 mile radius
circumference of a circle = 2*pi*radius or diameter*pi
