Answer:

117π or 367.56634047

Step-by-step explanation:

Volume = π × r² × h (r=radius and h=height)

Volume = π × 4² × 13

Volume = π × 9 × 13

Volume = π × 117

Volume = 117π

can anyone help? here is the question: emily had y baseballs cards. she shared her baseballs cards equally among her four cousin

stealth61 [152]

So if Emily had y baseball cards and distributes them evenly among 4 cousins and herself, then you would start off with y / 5 (don't forget herself) and then she gives 6 of them to her brother the final expression would be

Select the two statements that are true about the equation y−56=4(x+5)y-56=4(x+5).

Sergio [31]

The correct answers are:

The slope of the line is 4.

A point on the line is (−5, 56)

Step-by-step explanation:

Given equation is:

$y-56=4(x+5)$

The slope-intercept form is:

$y-y_1=m(x-x_1)$

Comparing both equations we get

m = 4

$y-56=y-y_1\\y_1 = 56\\x+5 = x-x_1\\x_1=-5$

The point is (-5,56)

So, the correct answers are:

The slope of the line is 4.

A point on the line is (−5, 56)

ind the probability of answering the two multiple choice questions correctly if random guesses are made. Assume the questions ea

algol13

Answer: a. 0.04

Step-by-step explanation:

Given : Number of multiple choice questions = 2

Choices given in each question = 5

Since only one choice is correct out of 5.

So, the probability of selecting the correct answer = $\dfrac{1}{5}$

Also, both questions are independent of each other.

It means , The probability of answering the two multiple choice questions correctly if random guesses are made

=( Probability of selecting the correct answer in question 1 ) x ( Probability of selecting the correct answer in question 2 )

= $\dfrac{1}{5}\times\dfrac{1}{5}= 0.04$

Hence, the required probability =0.04
