Answer:
Rate of change of the diameter is equal to 0.053cm/min
Step-by-step explanation:
A snowball is of the shape of a sphere
Surface area of Sphere (S)= 
Rate of change of surface area
dS/dt = -4
the negative sign indicates the surface area is decreasing.
Radius = d/2 where d represents diameter
using this is the surface area equation
S = 
= 
dS/dt = 2*pi*d*d(d)/dt
4 = 2*pi*d*(d)/dt
d(d)/dt = 2/12*pi= 
cm/min
so the rate of change of the diameter is equal to 0.053cm/min

3.2/4
4. 8/10
Step-by-step explanation:
basically the idea is to find something in the same fact family so like the example on 1, follow that and try to answer the next problams on your own its really easy
( sorry if im wrong or not i tried to help)
Looks like it should be D since they spent 0.08 on tickets and get 1.92. Then shirts are $55 so we subtract this from the profit.
