Answer:
The given expression
on multiplying is 
Step-by-step explanation:
Consider the given two expressions
and 
We have multiply both expressions,

To multiply two terms first multiply constant numbers that is 6 × 2 = 12
For x , y and z apply property of exponent,

Then power of x together will be,

Similarly for y powers,

Since first term do not have any expression for z so it will remain same.
Thus, the given expression on multiplying become,
is 
Answer:
The correct option is D.
8π = 1/3 * π * (r)² * 6
Step-by-step explanation:
First of all to solve this problem we have to know the formula to calculate the volume of a cone
v = volume = 8π
r = radius
h = height = 6cm
π = pi
v = 1/3 * π * r² * h
we replace with the known values
8π = 1/3 * π * (r)² * 6
If we look at the options, the correct option is D.
