Sarai uses 4 cm of face wash each night. the cylinder 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? round your answer to the nearest whole number.

Find the volume of the cylinder and divide by 2.

V = pi * r^2 * h

Plug in what we know:

V = 3.14 * 2.5^2 * 10

V = 196.25

196.25 / 2 = 98.125

So the container contains 98.125 of face wash.

Now we divide this by 4 to see how many days it will last her.

98.125 / 4 = 24.53 = 25

So the face wash will last her about 25 more days.

It’s 5 points actually
