Question 23+22 Maths 4H

[Brain Box]

i could do the question 23 because i didnt know whether to find the surface area for the sphere or the volume and the question 22, i solved it and got the middle and didnt know what to do. so does anyone how the question 22 and 23 should have been done?

Could you remind what the questions were asking for exactly? I can PM you the correct answers

the question about two spheres in the cylinder and you were asked to find the radius i thk and the 22 is about 5/(x-2) + 9/(x+2)(cant rilli remember)

23. Volume of cylinder - 2*volume of sphere = (the number given ,i cannot remember it) if you remember the question exactly post it.

22. the question was 5/x-2 + (it was not 9)/x+2 = 2
if you could remember the numbers i will give you the answer because i can't remember too
