Answer:
<h2>
V = 360π in³</h2>
Step-by-step explanation:
the formula for the volume of a cone of base radius r and height h is:
V = (1/3)(πr²)(h). Here, r = 6 in and h = 30 in. Then,
V = (1/3)(π)(6 in)²(30 in), or
= (1/3)π(36 in²)(30 in), or
V = 360π in³
Answer: Ok for the first two they are true.
Step-by-step explanation: So how you would do this is simple, so for # 2 2x-5=11 (x) represents a number and you have to find it. So For this one put an eight in the x's place and that makes 2(8)-5=11 so when you see 2x that mean 2 times what ever x is. so 2x8=16, 16-5 =11.
Answer:
y = 7 - 2x
Step-by-step explanation:
Note that:
y = height of the candle
x = hours
The candle starts at 7 inches, and can only grow smaller as it is burnt. It also burns in a constant 2 inches per hour. Note that it is "2 inches per hour, or 2 * h (h = hour). It is also burning, or taking away, from the original, or 7. Therefore, y = 7 - 2x is your answer.

Answer:
To solve for x in equation 
we should use Division property of equality.
Step-by-step explanation:
Consider the given equation
Division property of equality states when we divide both sides of an equation by same non zero number , then also both sides remain equal
Applying Division property of equality to the given equation
Divide both sides by 2.5
We get,
Thus, to solve for x in equation we should use Division property of equality.
