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
Answer:
The correct answer is 4.8 meters.
Step-by-step explanation:
Jamal stands on a dock 1.5 meters above the surface of the water.
A trout swims 4.8 meters below Jamal.
The trout must be swimming below the surface of water.
Therefore the distance below the surface of water where the trout is swimming is 4.8 - 1.5 = 3.5 meters.
But the vertical distance between Jamal and the trout is 4.8 meters only.
