Step-by-step explanation:
Given : Nathan brings cupcakes to school and gives them to his five best friends, who share them equally.
i.e. Number of friends = 5
If c represents the number of cupcakes Nathan brings to school, then the number of cupcakes each of his friends receive is given by using division operation :_
Hence, the expression to show how many cupcakes each of his friends receive. :
Answer:
Note: The expression "h =300- pi r /pi r" would equate to 299, as written. I find h = (300 - π )/πr to be the equation for height.
Step-by-step explanation:
The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius. That consists of top and bottom disks, each with an area of π, for a total of 2π
. The side is a continous sheet that has an area of 2πrh, where h is the height. 2πr is the circumference of the can, so the surface area of the side is 2πrh.
The total surace area of a closed cylinder is therefore 2π + 2πrh.
2π + 2πrh = 600
π + πrh = 300
πrh = 300 - π
h = (300 - π )/πr
