The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).
If you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km)
This the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).
The reason the answer's 40 million meters is because one meter was defined in 1793 as one ten-millionth of the distance from the north pole to the equator (you'd have to go 4 times further to go all the way around - hence - 40 million).
The circumference of the Earth is ~24902 miles or 40,076,000 meters. This speed of light is 299,792,458 m/s. So it takes 0.134 seconds to go around the earth once.
The speed of the moon around the Earth is approximately 1,022 meters per second.
An acceleration of 9.8 meters per second squared is equivalent to the acceleration due to gravity on Earth. This value represents the rate at which the speed of an object changes per second when it falls freely under gravity near the Earth's surface.
"Meters" is not a unit of acceleration.The acceleration of gravity on or near the surface of the Earth is about9.8 meters/second2 .It's different in other places.
What they thought was the circumference of the Earth.
The circumference of the Earth measured at the equator is 24,901.55 miles, or 131,480,184 feet or 40,075.16 kilometers, or 40,075,160 meters.
The Earth's circumference is approximately 40,075 kilometers, which is 40,075,000 meters. A 30 cm ruler is 0.3 meters long. To find out how many rulers are needed, divide the Earth's circumference by the length of the ruler: 40,075,000 meters ÷ 0.3 meters/ruler ≈ 133,583,333 rulers. Therefore, you would need about 133.6 million 30 cm rulers to measure the Earth's circumference.
The circumference of the Earth is just a tad over 40,000,000 meters. This isn't a coincidence; the meter was supposed to be exactly 1/40,000,000 th of the Earth's circumference, but they missed it by a little.
-- Exact circumference = 2pi meters -- Approximate circumference = 6.283 meters
Measure the diameter of a penny, convert to meters, and divide the circumference of Earth (which is about 40 million meters) by this value.
A circumference of 21.99 meters.
A circumference of 50.27 meters.
The Earth's circumference is about 40,000 kilometers, that's 40 million meters.
The circumference of a circle with a diameter of 23 meters is: 72.257 meters.
The circumference of a circle with a diameter of 13.4 meters is: 42.1 meters (diameter x Pi = circumference).
40075.016 kilometers = 40,075,016 meters (just over 40 million meters). This figure is the approximate circumference of the Earth at the equator.
The circumference is 18.76 meters.
