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
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
