The volume of the above figure is?
e-lub [12.9K]
Hello!

First, we must calculate the area of the base by using the formula, which is 3.14 × r × r × h

(I cannot access symbols on my device right now, otherwise I would've used the pi symbol and squared. Sorry, dude/dudette!)

Substitue:

A = 3.14 × 9 × 9

A = 28.26 × 9

A = 254.34 cm squared

Next, we must multiply the area of the base by the height to find the volume:

V = 9 × 254.34 squared

V = 2,289.06

Since there is no option for 2,289.06,the volume for the figure above is D. None of the above.

Your English teacher has decided to randomly assign poems for the class to read. The syllabus includes four poems by Shakespeare
Tresset [83]
The probability of event A and B to both occur is denoted as P(A ∩ B) = P(A) P(B|A). It is the probability that Event A occurs times the probability that Event B occurs, given that Event A has occurred.

So, to find the probability that you will be assigned a poem by Shakespeare and by Tennyson, let Event A = the event that a Shakespeare poem will be assigned to you; and let Event B = the event that the second poem that will be assigned to you will be by Tennyson.

At first, there are a total of 13 poems that would be randomly assigned in your class. There are 4 poems by Shakespeare, thus P(A) is 4/13.
After the first selection, there would be 13 poems left. Therefore, P(B|A) = 2/12
Based on the rule of multiplication,
P(A ∩ B) = P(A) P(B|A)P(A ∩ B) = 4/13 * 2/12
P(A ∩ B) = 8/156
P(A ∩ B) = 2/39

The probability that you will be assigned a poem by Shakespeare, then a poem by Tennyson is 2/39 or 5.13%.

Solve 8x+c= k for x.
Anon25 [30]

Answer:

x =  (k-c)/8

Step-by-step explanation:

8x+c= k

Subtract c from each side

8x+c-c= k-c

8x = k-c

Divide each side by 8

8x/8 = (k-c)/8

x =  (k-c)/8
