ok you need formula for surface area.
SA = πrh+2πr^2
Plug in 25 and 5
SA = 2π(5)(25)+2π(5)^2
SA = 10pi*25 + 2pi(25)
SA = 250pi + 50pi
SA = 300pi
Hope this helps :)

Answer:
1 quart = .947 L
3 Q = 2.841 L
So you should use 2.841 L to dissolve the powder
3x + 5x = 320
8x = 320
x = 40
3(40) : 5(40) = 120 : 200
The best answer would be Option C.
