Answer 1

What is your question based of this information?

Answer 2

give me a sec

Answer 3

@jyoung. take your time

Answer 4

its all there now ?

Answer 5

i gotta text book ;););) other then that nah

Answer 8

IDK how to start this all

Answer 9

same thats kind why im here doe

Answer 10

I can give you some tips. First, find the formula for a cylinder. The height of this cylinder is 39 due to the fact that the three balls have a diameter of 13. The radius would be 7.5 as half the diameter is the radius. You can find formulas here. If you can't get the answer, tag me in this after you tried. http://www.science.co.il/Formula.asp

Answer 11

hmm cant find it

Answer 12

@HanaMalik you got this now??

Answer 16

so than in this cylindrical container there are 3 balls with diameter 13 cm.
the balls just touch the top,bottom and sides of the cylinder

a. what is the volume of the cylinder ?

Answer 17

@Seratul 13 halfed is 6,5 not 7,5 how you have wrote there above ---Attention please !!!

Answer 18

b. formula for volume of a sphere is V= 4pir^3/3 so in this case

V of a ball = 4*3,14*6,5^3/3
V of a ball = 1149,76 cm^3
V of the 3 balls = 3* 1149,76 = 3449,28 cm^3

c. what percent of the volume of the container is occupied by the 3 balls ?
use the rule of 3 simple

V of container is 5173,935 cm^3 ----- 100%
V of 3 balls is 3449,28 cm^3 -------- x%
-----------------------------------------

x = (3449,28*100)/5173,935 = 66,66%

x = 66,66%

this mean that these 3 balls occupied 66,66% of the volume of the container
- hope so much that these above wrote will help you sure easy understanding what is the way how you can solve this your exercise right sure easy

good luck

bye bye
