The spaceship travels 100 360ths of a circular orbit where the full orbit length, l ,(the circumference) is obtained by the formula
l = 2πr (where π=pi)
so the distance travel by the spaceship, d, is
d = (100/360)x 2 x π x7200 = 12566km (to nearest km)
l = 2πr (where π=pi)
so the distance travel by the spaceship, d, is
d = (100/360)x 2 x π x7200 = 12566km (to nearest km)
