Calculate the length of sides and determine whether triangle is a right triangle.
Earth circumference math. Find the 12 find the equation of the circle with center 3 7 and circumference 8π units. Side b is 1 cm longer than c side c is 31 cm longer than side a. The following figure shows how eratosthenes s earth measurement worked. Thus if one measures the distance.
Eratosthenes thought the following way. Eratosthenes some 2 200 years ago was off by only 125 km or 101 mi. Well the difference in angle between these two cities is equal to 7 12 which is 50 56 times less than a full circle. Earth s circumference is the distance around the earth.
Measured around the equator it is 40 075 017 km 24 901 461 mi. Measurement of earth s circumference has been important to navigation since ancient times. Triangle has a circumference of 90 cm. Measured around the poles the circumference is 40 007 863 km 24 859 734 mi.
