Answer:
V= 904.896cm^3
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of a cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
h - 18cm
d - 8cm
d = 2 * radius
r = d/2
r = 8/2
r = 4cm
π - 3.142
Insert the values into the formula of volume of a cylinder
V = πr^2h
V = 3.142 * 4^2 * 18
= 3.142 * 16 * 18
= 904.896cm^3

Answer:
The volume of this cylinder is 9184.5 cubic feet.
Step-by-step explanation:
The area of a circle is and the volume of a cylinder with that base is just that area times the height:
Here, we're given the diameter, but we need the radius. The radius of a circle is just half of the diameter:
Next, you can use that radius to calculate the area of the base:
Finally, multiply that by the height to find the volume of the cylinder:
The volume of this cylinder is 9184.5 cubic feet.
Answer:
The probability that there will be more than one Phillips head screw = 0.1803 .
Step-by-step explanation:
We are given that there are 11 two-inch screws in a box of which 4 have a Phillips head and 7 have a regular head.
We are selecting 3 screws randomly from the box with replacement, so the probability that there will be more than one Phillips head screw is given by :
- <em>Probability of selecting two Phillips head screw.</em>
- <em>Probability of selecting three Phillips head screw.</em>
Now P(selecting 2 Phillips head screw with replacement) is given by :
Selecting 2 Phillip head screw = * =
P(selecting three Phillips head screw) = * * =
Therefore, Probability that there will be more than one Phillips head screw
= + = = 0.1803 .
