The volume of a cone varies jointly with the area of the base and the height. when the area of the base is
strojnjashka [21]
The volume of a cone varies jointly with the area of the base and the height of the cone.

V = kAh

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

V = \dfrac{1}{3}Ah

Now we use the second set of info, the height and the volume, and we find the area of the base.

V = \dfrac{1}{3}Ah

124 = \dfrac{1}{3} \times A \times 12

124 = 4A

A = 31

Answer: the area of the base is 31 cm^2

Which expressions are equivalent to this expression?
Lyrx [107]

Answer:

Option B

Option C

Option D

All of these are correct

Step-by-step explanation:

Option B is correct because:

2x + 1 + 2x + 3 = 4x + 4

=> 4x + 4 = 4x + 4

Option C is correct because:

x + 3x + 4 = 4x + 4

=> 4x + 4  = 4x + 4

Option D is correct because:

2(2x + 2) = 4x + 4

=> 4x + 4 = 4x + 4

Option A is incorrect because:

4(x + 4) = 4x + 4

=> 4x + 16 ≠ 4x + 4
