Question

EarthSat has a circular orbit with a radius of 175 kilometers (km) and swept out

an angle of 3 radians. MoonSat has a circular orbit with a radius of 160 km and
swept out an angle of 4 radians in the same span of time. Which satellite traveled
a greater distance in that span of time? Be sure to explain your reasoning.

Answer 1

Explanation:

One full orbit of the satellite is 2π radians. Therefore, 70% of a full orbit is 2π(0.7)=1.4π radians.

therefore the answer is 2.

(im not 100% precent sure its right :) )
