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.
Note a diameter is 2*the radius and 1 kilometer = 0.62137119224 mile. Equatorial radius of Uranus is 25,559 ± 4 km Polar radius of Uranus is 24,973 ± 20 km
circumference of a circle = 2*pi*radius or diameter*pi
Radius = Diameter/2 Diameter = 2* 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".
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
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
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
