Answer:

Step-by-step explanation:
In the Equation it asks for 3 things; pi (3.14), r (The radius), and h (the height).
In the question, it says that the radius is 1 foot and that the height is 4 feet. From there all you need to do is insert those numbers where it's shown in the equation. This makes the equation go from this:

To this: 
From there you follow PEMDAS/GEMDAS. And should have your answer.
Answer:
4 m
Step-by-step explanation:
The circumference of a circle is the product of π and the diameter.
C = πd
12.56 m = 3.14d
d = 12.56 m/3.14 = 4 m
The rug's diameter is 4 meters.
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
