Answer:

Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The volume of the figure is equal to the volume of the cube plus the volume of the square pyramid
<em>Find the volume of the cube</em>

where
b is the length side of the cube
we have


Find the volume of the square pyramid

where
b is the length side of the square base
h is the height of the pyramid
we have


substitute


<em>Find the volume of the complete figure</em>
Adds the volumes

convert to mixed number

Answer:
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)h
=(1/3)*3.14**9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
Step-by-step explanation:
Answer:22m+42
Step-by-step explanation:
7•2m =14m + 8m = 22m
7•6=42
2 goes into all the terms so;
2(-2x² + 7x - 3) now you could factor it:
2(-2x - 1)(x + 3)
