Answer:
A: radius of the sphere
Step-by-step explanation:
The formula for surface area is A = 4πr^2
With r being the radius and A the surface area.
For volume it is
V= (4/3)πr^3
So... hmmm if you check the first picture below, for 2)
we could use the proportions of those small, medium and large similar triangles like

now.. for 3) will be the second picture below
10% of 3.99=0.399x4=1.596
1% of 3.99=0.0399x5=0.1995
1.596+0.1995=1.7955
1.8(Rounded)+3.99=5.79
