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.
It is half of the diameter or radius = diameter/2
Earths mean diameter is 12756km at the equator, Mercury's diameter is 4879km. Mercury diameter is 0.3824 of Earths (if Earth is 1), or put another way, Earth diameter is 2.6 times bigger than that of Mercury.
Mercury's diameter is about 3032 miles (4879 km), which is about three-eighths of Earth's diameter (about 38%).Earths volume is around 17.86 times that of Mercury's volume.Earth's radius is 2.61 times that of Mercury and 18.18 times the mass.
That depends what you mean by "size". Diameter: 0.38 times the diameter of Earth. Radius: same number, since the radius is half the diameter. Volume: the ratio of the diameters cubed. Mass: 0.055 times Earth's mass.
Mercury's diameter is 4879 km or 3,032 miles.
Mercury is the closest planet in size to the Moon. Mercury is only slightly larger than the Moon, with a diameter that is about 38% larger.
I suppose you mean how much is Mercury's diameter. According to the Wikipedia, Mercury has a radius of about 2440 km. The diameter is twice that amount, and if you want to convert that to meters, just multiply it by a thousand.
Radius = Diameter/2 Diameter = 2* Radius
The diameter of Mercury is approximately 4,880 kilometers.
Mercury has a radius of 2440 km (1510 mi) and the diameter is 4880 km (3020 mi). Is about the same density as Earth.
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.
