Can someone please tell me if my answer is correct. I'm working with radicals.

b. Suppose that an object is 100 pounds when it is at sea level. Find the value of C that makes the equation true. (Sea level is 3,963 miles from the center of the Earth.)
C=wr^2 C=100(3,963)^2= 157,053,690,000
C=157,053,690,000

should have gotten 1,570,536,900. It looks like you have an extra 0 at the end.

i got 1,570,536,900. two too many zeros, but your math was right other than that!

jim_thompson5910 · Answer

I looks like you squared 100 as well, that would explain the 2 extra zeros.
