r=d/2
to find radius, you divide the diameter by 2 or multiply it by one half
Answer:
The fluid friction or drag can be reduced are minimised by giving special shape called streamlined shape to the objects which Move through fluids like air or water
That can only be happening if the mass mysteriously increased somehow. I'd like to know how in the world THAT happened.

Explanation | Common mistakes | Hint for next step
Time taken to complete one resolution is 365 days. Convert time from days into seconds. Radius of earth orbit around the sun is given. Velocity is circumference of orbit upon time taken in one resolution. Calculate the magnitude of earth velocity. Change unit of velocity to
