The circumference of a circular grass is 31.416meters.find the diameter and area of grass?
Divide the known circumference by the value of Pi - and you'll have your answer !
How do you find an experimental value of pi?
The ratio of C to D will equal pi. This is based on the known formula for the circumference of a circle. D = Diameter of the circular base of a cylinder (independent) C = Circumference of the circular base of a cylinder (dependent)
When did euratosthenes calculate the circumference of the earth?
It is not known when, or even if, Euratosthenes did calculate the circumference of the earth. However, it is known that a very accurate estimate was obtained by Eratosthenes in the early years of the third century BC.
How far is the earth around?
about 24900 miles or 40072,6 kilometers also known as the circumference.
What is the perimeter of a circle known as?
The circumference

What are the contribution of aristarchus?
Postulated that the Earth is curved and calculated the circumference of the Earth to within 1% of accuracy, simply by using shadows and geometry; then placed the sun at the center of the then known solar system - known as the heliocentric universe.
What is the circumference of the planet earth?
From the equator the earth is 24,901.55 miles in circumference or 40,075.16 kilometers. Measured from North pole back around to North pole, the circumference is 24,859.88 miles or 40,008 kilometers.

What is Eratosthenes?
He was an ancient Greek mathematician of the 2nd/3rd century BC, as well as a poet, geographer, musical composer, scholar, and astronomer. He was the first Greek to estimate the circumference and tilt of the earth. He created a map of the earth based on the knowledge available at the time. He was highly respected, and his calculations of the earth's circumference were used for hundreds of years. Today, his method for finding prime numbers from 1-100 is known as the 'Sieve of Eratosthenes' and is taught in math textbooks.

What is the distance around the edge of a 2 dimensional shape known as?
The distance around a two dimensional shape is known as the perimeter of the shape. If the shape is circular, it may be refered to as a circumference.
How far is the earth around?
about 24900 miles or 40072,6 kilometers also known as the circumference.
What shape is known as a circumference?
The perimeter around a circle is known as its circumference
What is the perimeter of the earth?
The earth does not have a perimeter. The Perimeter is the distance around a circle. The earth is not a circle, but a sphere (sort of). The measurement around the earth is the circumference. Because the earth is not a perfect sphere, the circumference is different depending on whether you measure it horizontally (the equator) or vertically through the poles (Meridian).
What is the earth's polar circumference?
The metre was originally defined as one ten-thousandth of one fourth of the Earth's Polar circumference. i.e. 10 000 m from equator to pole. Giving a total polar circumference of 40 000 km. If fact the measurement was slightly in error, but the magnitude of that error is known.
What is distance around and through the Poles is?
The circumference of the earth at the equator is 40,075.16 kilometers or 24,901.55 miles.The shorter circumference of the earth over the poles is 40,007.86 kilometers or 24,859.73 miles.The difference is 67.3 kilometers or 41.82 miles.This shape is known as an ellipsoid or more properly, a geoid (earth-like).
