Kelly has 3/4 of a pie left. she wants to split the pie with 3 of her friends. how much of the pie will each person get?

Each of her friends will receive 1/4 of the pie. There were four pieces of the pie, if there are three even pieces now and there are three friends. Each one will get 1 slice each.

we want to do 3/4 divided by number of friends

remember that (a/b)(c/d)=(ac)/(bd)

3/4 divided by 3=

3/4 times 1/3=

(3*1)/(4*3)=

3/12=

1/4

each friend gets 1/4 pie

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
