Answer:

AB = 13.964 cm

Step-by-step explanation:

BF² = 6² + 13²

BF² = 36 + 169

BF² = 205

AB² = AF² - BF²

AB² = 20² - 205

AB² = 400 - 205 = 195

AB = 13.964 cm

How many times greater is the volume of the large bowl than the volume of the small bowl
arsen [322]
Answer: it depends on how big each bowl could be. depending on how big the diameter of the bowl is, we can figure out what the radius is, and then we could multiply that by pi squared, which gets you the area of the circle. Then we could figure out how much larger the large bowl is than the smaller bowl with the diameter knowledge that we gained.

So, for example, there was a bowl like this: (|||) (imagine that is a full circle) and that would be... about 9 in. across. imagine the smaller bowl is about 3in. across. then, we could figure out the radius by finding the middle, and expand the middle to the edge of the bowl. then, whatever the radius is, we could multiply that by 8, and get the total diameter of the bowl in inches. with that knowledge, we should be able to know the area of the bowl, by getting the diameter, and multiplying it by pi squared which equals 9.42, and then you multiply that by the radius and the diameter to get the area of the bowl.


that is how you could figure out how much bigger the large bowl is than the smaller bowl.

40.186 Mb

Step-by-step explanation:

14.2% of 283 megabytes have been downloaded.

To find a percent of a number, multiply the percent by the number. Change the percent to a decimal by dividing the percent by 100 which means move the decimal point of the percent two places to the left.

14.2% of 283 Mb =

= 14.2% * 283 Mb
