Earth is 149.6 billion meters from the sun and takes 365 days to make one complete revolution around the sun. mars is 227.9 billion meters from the sun and has an orbital period of 687 days. what is the ratio of earth’s centripetal acceleration to mars’s centripetal acceleration?

what is the actual question though?

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
