The average diameter of the orbit of the earth around the sun is 2992 km.
a) find the radius in kilometers in the form ax10^k where 1 ≤a < 10.
b) round the measurements to 2sf. keep answers in scientific notation for parts b-d
c) it takes one year for the earth to complete one full orbit. assuming the orbit is a circular path, calculate the distance in km that the earth travels in one orbit around the sun
d) today’s is mary’s 17th birthday. calculate the total distance that he has travelled around the sun since being born accurate to 2sf.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
