Question

The sum of radii of two spherical balls is 22cm and the difference of their volume is 3050 2/3 cm3. Find the radii of the balls. (take pie=22/7)

Answer 1

r+R=22
PI (r^2-R^2)=3050 2/3

in equation one, solve for r.
Put that into equation 2, and expand to solve for R. There ia a bit of algebra and quadratic equations to navigate.

once you have R, solve equation one for r

Answer 2

Thank you so much. I really appreciate it.

Answer 3

Text book answers doesnt match my answers. What should i do?

Answer 4

i think you've gotten volume mixed up with area. volume formula is 4/3 pi(r)^3 and area formula is pi(r)^2
