You can just google volume of a sphere calculator and plug the radius (3 cm) in :)
Step-by-step explanation:

so A = 64a +45
(
so B = 108 +a
2A-B=0--> 2(64a+45)-108-a=0--> a =18/127
2x - 10 + 3x - 10 = 90
5x - 20 = 90
5x = 90 + 20
5x = 110
x = 110/5
x = 22
2x - 10......2(22) - 10 = 34 <== one angle
3x - 10......3(22) - 10 = 56 <== the other angle
By defferentiating the about using product rule
vdyu/dx +udvdx
dy/dx 4×^3 +6×^2-4× -4=o
Answer:2x -3y=9 .
