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".

To find the area of a rectangular prism multiply length by width by height.
If the problem has a variable take the two other dimensions and multiply them together. Then take that number and subtract it from the total to find the number that the variable equals.
Answer:
e(x) x2+6x+21=53
m(x) 8x=32
v(x) 31x=124
therefore v(x) is the correct answer
