2= slope
Answer:
48π
Step-by-step explanation:
Given that,
The radius of the sphere is increasing at a rate of 3cm/minute,
The volume of a sphere is given by :
Differentiating both sides wrt t.
Put r = 2 cm and dr/dt = 3 cm/minute
So,
Hence, the correct option is (a) "48π".
Answer:
k=3
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In this problem we have
therefore
The constant of proportionality is k=3
If the radius is tripped, the volume will increase by 3^3 = 27 times.
Answer: 27 times
