What is the total volume of this compound shape?
Alex787 [66]

Answer:

This is very easy. First find the volume of the cube, and then add it to the volume of the hemisphere to find the total volume.

The volume of the cube is length x width x height: 8 x 8 x 12 = 768 cm

The volume of the hemisphere is (2/3)πr³ : (2/3)π(4)³ = 134.04 cm

*Radius is 4

Now add: 768 + 134.04 = 902.04 cm

Which expression is equivalent to (it is in the attached)
Alla [95]

Answer:

The answer to your question is the first option

Step-by-step explanation:

                   \sqrt[4]{\frac{24x^{6} y}{128x^{4} y^{5}}}

Find the prime factors of 24 and 128

                    24    2                     128   2

                    12     2                       64  2

                     6      2                       32 2

                     3      3                       16  2

                      1                                8   2

                                                        4   2

                                                         2   2

                                                         1

                   24 = 2³ 3                    128 = 2⁷              

                   \sqrt[4]{\frac{2³3x^{6} y}{2⁷x^{4} y^{5}}}  

Simplify

                   \sqrt[4]{\frac{3x^{2}}{2^{4} y^{4}}}

Simplify the root and result

                  \frac{\sqrt[4]{3x^{2}}}{2y}
