What is the answer and explanation to sarai uses 4 cm3 of face wash each night. the cylindrical container of face wash is 10 cm tall and has a diameter of 5 cm. the container is half empty. how many more days will the face wash last her? use 3.14 to approximate pi, and round your answer to the nearest whole number. need answer asap

So you have to calculate the volume

volume=height times area of base
area of base=area of circle=pi r^2
volume=hpir^2

we need radius but we are given diameter
2r=d
r=d/2
d=5
r=5/2=2.5

height=10
pi=3.14 for this question

so
volume=10 times 3.14 times 2.5^2
volume=31.4 times 6.25
volume=196.25

volume of face wash is 196.25
it is half empty
196.25 times 1/2=98.125 cm^3

so
4 cm^3 used every niehgt
so
x=number of nights
4 times x nights=volume of remaining
4x=98.125
divide boht isdes by 4
x=24.53
round to nearest whole number
25

answer is 25 days
