Question

my teacher put an example on board of mercury's orbit of .436 now we need to get circumference of orbit. She put c=2(3.14)r then she put c=2(3.24).436. Shouldn't it be c=2(3.14).436

Answer 1

yes simple typo. should be 3.14 as the circumference equation is \[2pir\]

Answer 2

that's assuming the orbit is circular... but in the case 3.24 appears to be an error

Answer 3

thankyou and she repeated it without catching and gave us answer to write on paper to go with other planets

Answer 4

no problem
