Answers

Answered by Jennifer
The period is given by

T = 2 * pi * (r^3/(G*M))^0.5

where T is the period, r is the radius, G is the gravitational constant, M is the mass of the earth

convert 621 km to meters
look up the Gravitational constant and the mass of the earth in kg

plug in the numbers, and solve
