Just did this in my trig class yesterday.
Arc length = radius * theta(radians)
Circumference of Earth = radius of earth * 2pi
Note: The arc length is the circumference of the Earth only in this case because theta is equal to 2pi.
Circumference = 2*pi*radius
circumference = π x diameter π = 3.14159...
Thee formula for the circumference of a circle should read 2*pi*radius or pi*diameter. In which case using either formula its circumference is 88 inches rounded.
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
Multiply the diameter by the constant pi.
Eratosthenes of Cyrene was a Greek mathematician, elegiac poet, athlete, geographer, and astronomer. He was the first person to calculate the circumference of the earth by using a measuring system using stades, or the length of stadiums during that time period, and the tilt of the earth's axis.
Circumference = 2*pi*radius
An arc is part of a circumference of a circle. The circumference itself is an arc length. The circumference of a circle is found by using the formula circumference (C) is equal to 2 multiplied by pi and the radius, or 2 x pi x r, where r is the radius and pi is 3.14.
circumference = π x diameter π = 3.14159...
the circumference of a circle is the length around the outer edge. and you find it by using the formula 2 times pi times the radius of the circle
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
Thee formula for the circumference of a circle should read 2*pi*radius or pi*diameter. In which case using either formula its circumference is 88 inches rounded.
The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.
The circumference of a circle with a radius of 6.74 inches is approximately 42.34 inches. The circumference of a circle is found using the circumference formula: Circumference = 2 * π * radius So, all you have to do is plug in the radius into the formula, and approximate π to be 3.14159.
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
The circumference of a circle with a known radius and can calculated using the following formula: C = 2Π(r)
Multiply the diameter by the constant pi.
