The volume of a cylinder is 525 cm3. The radius of the base of the cylinder is 5 cm. What is the height of the cylinder? The hei
elena-14-01-66 [18.8K]

you do not give a value for PI so I am using 3.14

V=PI x r^2 x H

you know volume and radius so put those into the equation

525 = PI (3.14) x 5^2 x H

525 = 3.14 x 25 x H

525 = 78.5 x H

divide both sides by 78.5

6.687 = H

round off answer as needed 6.7cm or 6.69cm

 NOTE : the answer may vary slightly depending on the value of PI used.

 but this is how you calculate the height.

use the frequency table to find the probability of at most 4 responses received to this week's newspaper editorials.
ZanzabumX [31]

Answer:

B


Step-by-step explanation:

To get probability of AT MOST 4 responses means all the probabilities Equal to or Less Than 4.


<u>From the table, that is probability of 0, 1, 2, 3 or 4</u>. <em>(OR in probability means adding)</em>

<em>Hence, we add the number of editorials for P=0,1,2,3, and 4 and then divide by total number of editorials.</em>

P(\leq4)= \frac{20+30+56+38+34}{200}\\P(\leq4)=\frac{178}{200}\\P(\leq4)=0.89

Answer choice B is right.
