Volume of cylinder = π × (radius)² × (height

V = π × (8/2)² × h

V = 16 π h

V = π (8h) 2

Answer:

The correct answer is option A

Step-by-step explanation:

The volume of a cylinder is given by

V = \pi r^{2} h\\

Substituting the values of radius and height in above equation, we get -

radius = \frac{diameter}{2} \\radius = \frac{8}{2} \\radius = 4 feet\\V = \pi 4^{2} h\\

HELP ASAP<br><br><br>What is the ratio 25 to 65 written as a fraction in lowest terms?​
alekssr [168]

The GCF (Greatest Common Factor) of 25 and 65 is 5. So, we can divide both numbers by 5.

25 / 5 = 5

65 / 5 = 13

Now, put it into a fraction.

5/13

This cannot be simplified any further.

Best of Luck!

What is the equation of a circle centered at the origin with radius 15?
sashaice [31]

Answer:

D

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

Here r = 15, thus

x² + y² = 15² , that is

x² + y² = 225 → D

Data will be collected on the following variables. Which variable can be considered discrete? A. The height of a person B . The
kvv77 [185]

Answer: E: The number of books a person finished reading last month

Step-by-step explanation:

First, a discrete variable is a variable that only can take some given values in a set, the discrete variables are usually not dense, and a continuous variable is a variable that can take any value in a range (where the accepted values are dense).

So, for example, the set of the natural numbers is discrete, and the set of the real numbers can represent a continuous variable.

Here the only option that is really discrete will be the number of books that a person finished reading last month because here only positive whole numbers are accepted (you can not finish a 0.454 of a book)

The other options are continuous because all are classical measures.

For example, the weight of a person can jump between:

75.6kg and 75.7kg.

So you could think that this is discrete because the values between 75.6kg and 75.7g are not shown with our measuring device, but those will be added in the error of the measure because the weights between 75.6kg and 75.7kg are actually possible, so they must be accepted.

What should be done to both sides of the equation in order to solve y + 8.5 = 17.2?
Amanda [17]

Answer:

Subtract 8.5

Step-by-step explanation:

To solve the equation, y has to be isolated (only y will be on one side of the equation)

To do this, we have to get rid of the 8.5, so it has to be subtracted from both sides.

So, the correct answer is subtract 8.5
