inner core
The inner core of the Earth is a solid metallic sphere made primarily of iron and nickel with a radius of about 1216 kilometers. It is surrounded by the liquid outer core and the solid mantle.
The inner core is approximately 1271 kilometers in radius and is composed of iron and nickel, the liquid outer core is 2270 kilometers radius, and the radius of the mantle, the thickest solid layer, is 2885 kilometers.
The radius of Earth is approximately 6,371 kilometers.
The inner core of the Earth is about 1,220 kilometers (758 miles) in radius. It is a solid metallic sphere composed mainly of iron and nickel, with temperatures reaching up to 5,700 degrees Celsius (10,300 degrees Fahrenheit).
The smallest sphere of the Earth is its inner core, which is a solid ball composed mainly of iron and nickel. It is approximately 1,220 kilometers in radius and is surrounded by the outer core, mantle, and crust.
The Earth's radius is approximately 6,371 kilometers and 3,959 miles.
Ceres has an average radius of about 470 kilometers; Earth's radius is about 6371 kilometers.
Venus has a radius of about 6,052 kilometers, which is about 95% of Earth's radius.
The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2. "r" is the radius; if you find the diameter of Earth somewhere, divide it by 2 to get the radius.The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2.

inner core
That would be the radius of the earth which is:6,378.1 kilometers
The radius of the Sun is approximately 696,340 kilometers (432,685 miles), while the radius of the Earth is approximately 6,378 kilometers (3,959 miles). Therefore, the difference in radius between the Sun and the Earth is approximately 690,962 kilometers (428,726 miles)
