Acylinder shaped dispenser holds 5,652 cm³ of liquid soap and is now full. the radius of the dispenser is 7.5 cm. what is the difference between the height of the soap in the full dispenser and the height when 4,239 cm³ of soap remains in the dispenser? use 3.14 to approximate pi.

30cm is the difference between the height of the soap in the full dispenser and height of the remaining soap. 

The formula for cylindrical height is: 

  Area
       -  r
2 * π * r

Cylindrical height of full dispenser.

      5652                            5652
  - 7.5    =    - 7.5  =  120 - 7.5 = 112.50
2 * 3.14 * 7.5                     47.1

Cylindrical height of dispenser with lesser liquid soap 
     
     4239                       4239
 - 7.5 =    - 7.5 = 90 - 7.5 = 82.50
2 * 3.14 * 7.5                47.1

Cylindrical height of full soap                112.50
Cylindrical height of lesser soap           - 82.50 
Difference in height of soap content       30.00 

Hope it helps! :D

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
