A hollow toy, with the dimensions shown in the figure, is to be stuffed with rigid foam. What is the maximum amount of foam that

Fudgin [204]

Option B: 67.02 cubic inches

<h2>Given that:</h2>

The diagram consists of two parts:

First a cone on the top with 12 inches height and 4 inches diameter.

Second a semi sphere with diameter of 4 inches.

<h2>Calculations:</h2>

The amount of foams that can be stuffed with foam is total volume of both the containers.

Volume of the given cone of 12 inches height and 4 inches diameter can be given as:

$\dfrac{1}{3} \times \pi \times 2^2 \times 12\\= 50.265 \: \rm inch ^3$

Volume of the semi sphere of 4 inches diameter can be given as:

$\dfrac{2}{3} \pi \times 2^3\\= 16.755 \: \rm inch^3$

Thus total volume is 50.265 + 16.755 = 67.02 cubic inches.

Thus option B : 67.02 cubic inches is the needed volume.

ANYONE GOOD IN MATH TRANSLATIONS??

Bumek [7]

Answer:

(x, y ) → (x + 2, y - 4 )

Step-by-step explanation:

Compare the coordinates of 2 corresponding points in the original and the image, that is

B(- 5, 4 ) → B'(- 3, 0 )

To translate from B → B'

We require a shift of 2 units right in the x direction and 4 units down in the y direction, that is

(x, y ) → (x + 2, y - 4 ) ← translation rule
