The volume of a cone varies jointly with the area of the base and the height of the cone.
where
V = volume
k = constant of proportionality
A = area of the base
h = height of the cone
The given info is for A = 27, and h = 6, then V = 54 (all using appropriate units for area, length, and volume, respectively.)
Now we can find k, the constant of proportionality.
V = kAh
54 = k * 27 * 6
k = 54/(27 * 6)
k = 1/3
The formula is
Now we use the second set of info, the height and the volume, and we find the area of the base.
Answer: the area of the base is 31 cm^2

Hello.
Here's our explanation: First, you had to multiply line them up. , then 3*3=9. Bring down the zero, then multiply 2*2=4. And 3*2=6, which gives us equal to 640. Finally, add it up, 96+640=736. 736 is the final answer.
Hope this helps!
Thanks!
Have a great day!
