Asked by Nancy

Using the formula, w = cr^-2,

solve for r. An object weighs 100lbs. What value of C will result in r = 3963?

I have another question similar, but if someone could guide me in this one, I can figure out the other one.

Thanks,

100 = c(3963)^-2

3963^-2 = √3963 = 63 (approx.)

100 = 63c

1.59 = c
