The diameter is 31 times 2 = 62 miles
200 miles
No. diameter = 2 x radius ⇒ radius = diameter ÷ 2 If the radius is 14 ft the diameter is 2 x 14 ft = 28 ft If the diameter is 7ft the radius is 7 ft ÷ 2 = 31/2 ft.
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.
circumference of a circle = 2*pi*radius or diameter*pi
The diameter of Uranus is approximately 31,763 miles (51,118 kilometers).
Radius = Diameter/2 Diameter = 2* Radius
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
Well the formula for the radius of the square is radius squared * pi (3.14)So find the radius (which is half of the diameter. which is exactly half of the shape)and do the formula. end the answer with "m".
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.
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
radius = diameter/2
A radius is half of a diameter. Example Diameter:4 Radius:2
