5) -7 (-15w + 21) + 3(18 - 27w)
Step 2: 105w - 81w - 147 + 54
6)
step 3: 24w - 93
Answer:

Step-by-step explanation:
Given
80.106
Required
Write in expanded form
First, we need the place value of each digit:

Next, we multiply each digit by its place value, to give the expanded form;

The volume of the cone will be 10 cubic units.
<h3>What is volume?</h3>
Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the cube or cuboid.
Given that:-
- The cylinder shown has a volume of 30 cubic units.
- The cone and the cylinder have the same height and the same base.
The volume of the cone will be:-
Vc = Vcyl

Vc = (1 / 3) Vcyl
Vc = ( 1 / 3 ) x 30
Vc = 10 cubic units
Therefore the volume of the cone will be 10 cubic units.
