For this case we have by definition, that the volume of a cone is given by:

Where:
A: It is the cone radius
h: It's the height
They tell us that the diameter is 21 m, then the radius is half the diameter, that is: 10.5m. The height is 4m. Substituting the data:
.
Finally, the volume of the cube is
ANswer:
Option B
When you know the coordinates of a point and the slope of a line, you can use the formula

in your case,
and
, so you have

Answer:
30%
Step-by-step explanation:
The answer is off by 30%, as the scale is off by 3 pounds. 3/10=30
Answer:
<h2>25</h2>
Step-by-step explanation:
So there is this property,
Sum of two angle of triangle = exterior angle
So based on this we can form an algebraic equation (NOTE: this is an equilateral triangle so all the sides are 60°)

So it's option B.
