Answer:

Step-by-step explanation:
The volume of a right circular cone is given by:

where r is the radius of the circle and h is the height of the cone, and
is a constant
.
According to the problem the height is:

and we don't have the radius but we have the diameter, which is useful to find it. We just divide the diameter by 2 to find the radius:

Now, we can find the volume by substituting all the known values:


Rounding the volume to the nearest tenth of cubic inch we get:

Answer:
$15
Step-by-step explanation:
You know that 3 pillows = $45
So you have to divide 45 by 3 to get the unit rate.
45÷3=15
Answer: 7/8
Step-by-step explanation:
To find the equivalent expression of a fraction, we can either multiply numerator and denominator by same variable or same number, or we can divide both numerator and denominator by same number or same variable .
So if we multiply both numerator and denominator by 2, we will get

I really don’t know look it up or something
