Answer:
see below
Step-by-step explanation:
SA of a cylinder = 2πr² +2πrh
________________________ = 2πr²/4πr² + 2πrh/4πr² =1/2 +h/2r
SA of a sphere = 4πr²
6500 : 125
1300 : 25
260 :5
52 :1
I am not sure about this... but it’s a.
The answer is 78
If you multiply 17x6 you get 102
102 equals the whole rectangle after that you need to get rid of the part that’s not there
so you multiply 8x3 which equals 24
you then subtract 24 from 102 and get 78
