To find the volume of a cylindrical object, you have to multiply the radius² by height by 
.
Since the question only asks about the volume of just the juice, and says that the glass is 3/4 full, you would take 3/4 of 8 centimeters, which would be 6 centimeters.
Now you would find the radius, which is half of the diameter. Meaning that 6 divided by 2 would be 3, making your radius 3 centimeters.
Now 3² is 9. 9·6 would be 54.
Your answer would be 54

Lan is 146 centimeters tall now.
<u><em>Explanation</em></u>
Let, Lan's current height is centimeters
As Lisa is 6 centimeters taller than Lan and Lan is 10 centimeters taller than Jim, so Lisa's current height = centimeters and Jim's current height =
centimeters.
Every month, their heights increase by 2 centimeters.
So, after 5 months.....
Lan's height = centimeters,
Lisa's height = centimeters and
Jim's height = centimeters
Given that, the sum of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in 5 months. So the equation will be....
So, the current height of Lan is 146 centimeters.
