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 outside circumference?
The outside circumference refers to the distance around the outer edge of a circular object. It can be calculated using the formula ( C = 2\pi r ), where ( C ) is the circumference and ( r ) is the radius of the circle. If the diameter is known instead, the formula can also be expressed as ( C = \pi d ), where ( d ) is the diameter. The circumference is important in various applications, including engineering, architecture, and everyday measurements.

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 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 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 Earth along the equator is radius or diameter or circumference?
The distance around the Earth along the equator is known as the circumference. It is approximately 40,075 kilometers (24,901 miles).
How do you measure the circumference of the earth?
Hm. You want the estimate or the actual data? The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers). However, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). Thus the earth is a tad wider than it is tall, giving it a slight bulge at the equator. http://geography.about.com/od/geographyglossaryc/g/ggcircumference.htm

The distance around the widest part of a planet?
The distance around the widest part of a planet is known as the planet's equatorial circumference. It is the longest distance that can be measured around the planet, passing through its equator. An example would be Earth's equatorial circumference, which is about 24,901 miles (40,075 kilometers).
What does the difference between the Earth's polar circumference and the Earth's equatorial circumference tell you about the Earth's shape?
The difference between the Earth's polar circumference and equatorial circumference, known as the flattening of the Earth, indicates that the Earth is an oblate spheroid. This means that the Earth is slightly flattened at the poles and bulges at the equator, making it not a perfect sphere.
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.
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.
