A Cylindrical container of salt is 6 inches and its base has a radius of 2 inches how much paper is neededto completly cover the container

Sagot :

so to cover the container is the surface area

to find the surface area, find the area of the 2 bases and the area around or
2(area of base)+(circumfernence times height)

so assuming 6=height

area of base=pi times r^2
circumference=2 times pi  times r

area of base=aprox 3.14 times 2^2
3.14 times 4
12.56
times 2

25.12


circumference=2 times pi times r
2 times 3.14 times 2
4 times 4.13
12.56
times height(6)
75.35

so ad them together

25.12+75.35=100.49 cubic inches

the answer is 100.49 in^3
