To solve this problem, we have to understand and establish some basic mathematical facts on a cone.
The answer to this question are option b and c only.
<h3>Cone</h3>This is a solid figure that has the base of a circle and the top is made up round triangle.
The formula of volume of a cone is given as
where;
In the given question, the first fact given is if the radius doubles the diameter and that false.
If we have the value of the the radius, we can calculated the base area using area of a circle
The volume of a cone is actually one-third the volume of a cylinder
we can only calculate the volume of the cone is we have the value of the height of the cone.
The answer to this question are option b and c only.

<u>Answer:</u>
The correct answer option is D.
<u>Step-by-step-explanation:</u>
We are given the following two functions:
and
We are to find so we will subtract the function g from function f, arrange the like terms together and combine them like shown below to get:
Therefore, is equal to
so the correct answer option is D.
.
Answer:
The dryer costs $325.
Step-by-step explanation:
Let <em>w</em> represent the cost of the washer and <em>d</em> represent the cost of the dryer.
They cost $587 combined. In other words:
The washer costs $63 less than the dryer. Therefore:
Thus, we have the system of equations:
We can solve it using substitution. Substitute the second equation into the first. Hence:
Combine like terms:
Add 63 to both sides:
And divide both sides by two. Hence:
The dryer costs $325.
Further Notes:
And since the washer is $63 less, the washer costs:
The washer costs $262.
